Are the Hella FF75 DRIVING Lights safe to use as low beams?
Are the Hella FF75 DRIVING Lights safe to use as low beams?
I know lots of people use these, but im just curious, ive never seen what the light projected from them looks like at night. anyoneh ave pics of the ff75 at night?
I was planning on buying 2 sets of these for low and high beams, and possibly ff50 for fog lights. I would be upgrading the bulbs to 130W with relay/12 ga wire, etc
Thanks guys
What is the best color temp to get? 4500K?
EDIT: Just realized I was in LT1 Tech when I posted this. Sorry!

there is more than enough light with just te factory 55w bulbs. but if you want to go bigger because it's always better, i'd stick with the 85x bulbs max. the deal witht the "driving lights" is, they are just that, driving lights. they arent headlights or fogs, they are very narrow and focused. i'd say that at about 30 yards or so they produce very good light. and then after that they gradually disperse. they dont light up the road like a headlight does, they dont produse 90* worth of light. i'd say they have about a 30-40* cone lighting effect.

There are loads of posts on this throughout the forums. But I have done the conversion and its sufficient to leave the stock Hella bulbs in the ones you get. Just point up your highbeams for long distance viewing.

They are not DOT approved for use as headlights and with 130w bulbs you're gonna be blinding everybody on the road. Brighter is not always better, it's the beam pattern that is most important. The Hella DOT projectors aren't going to be that much more $ than the FF75's. The beam pattern is awesome. Driving lights with 130w bulbs you will see down the road well but will miss the deer about to jump out in front of you on the side of the road.
If you blind a cop driving the other way, he's not gonna be real happy with you and could impound your vehicle for non-DOT headlights. It'd be cheaper in the long run to just go with legal, properly aimed beam pattern lights. Nicer to the oncoming drivers, too. Want some blinded DA to cross the centerline?
I would suggest running FF75/50 driving lights in place of factory fogs but I have FF50 fogs with 65w bulbs and get brighted. I don't get brighted with just the low beam Hella 90mm projectors but when I run with fogs and lows, I get brighted occaisionally. The fogs are aimed properly and have a very flat beam as opposed to a driving light's long range pencil beam.
Back in the days before non-sealed beams were DOT approved, I had a set of 7" round Cibie Z-beams hi/lows w/ H-4 80w/100w bulbs. Excellent beam pattern and cut-off but one night some chick swerved over the centerline when I topped a hill and temporarily blinded her (on lowbeams). I had to swerve onto the shoulder to miss her.

Re: Are the Hella FF75 DRIVING Lights safe to use as low beams?
so you think the FF75 with stock bulb for low beams and FF75 with a 100W bulb for the high beams would be good? and FF50 foglights?
What are the hella DOT projectors? Link? Price?

If I remember I can get pics later. I get brights once in a while, but all you do is point your highbeams up higher and flash yours back.
I have driven past about 4 dozen cops since I did the conversion and havent had one flash his brights or give me any problems. I think the problem people run into is pointing their LB too high and it gets in other motorists eyes.
Point the lows to where the stock ones were and the highs higher and only use the highs when no one is around.
I baught my FF75's for 37.99 a pair on ebay. The guys name was like offroad911, or something, and it was free shipping. Just go with them and point them correctly.
Also do a search in appearance for additional threads, there are many folks with this mod done and with pics on their websites.

bought the FF75 for the headlights and the FF50 for the fog lights.
what could I use to protect the fog lights from getting busted by rocks?
Also how do you do the mod to make all 6 lights stay on at the same time?

Re: Are the Hella FF75 DRIVING Lights safe to use as low beams?
Yes, they will be fine if you do that.
Speaking of broken lights, I checked mine today to find a pair broke from salt or stones on the freeway...Hope I can order the front plastic peice..

Re: Are the Hella FF75 DRIVING Lights safe to use as low beams?
Serene -- just sent e-mail, but, yeah, they'll work fine.
A general note for anyone considering this mod: driving beam pattern is better as low beam replacement than a fog beam pattern. A combination of both is preferable to get wide coverage and range. Fogs don't have near enough range for safety at legal road speeds ( not to mention the speeds some of us drive "Can I go 180mph with engine/gear combo?" ). They need to be aimed very carefully to minimize glare for oncoming drivers and maximize peripheral vision ( roadside visibility ).
I do NOT recomend anything higher than a 55w or 65w bulb in them. If you drive a lot of country roads at night, definitely upgrade the HIGHBEAM lights to a higher wattage but leave the lows low!
As a clarification to the combination of driving low beams and fogs, I mean a pair of normal wattage driving lights as lowbeams AND a pair of Aux fog beam lights. Though the thought of combining one of each as lows is interesting . . . fog on drivers side and driving beam on pass side. Hmm.
Anyway, my non-expert but fairly well-edumicated advice is specific to the type of night driving you do. This is for those that can't afford to do all lights at once ( most of us? lol ). Or just get the dang Hella 90mm's.
All or mostly lighted city streets: Upgrade existing fact. fogs ( or add if non-fact. equiped ) 1st with quality Hella, Cibie, KC Hilite, or Piia aftermarket fogs. Then upgrade the fact. lows with quality driving beam lights. Do the highs last.
More unlighted country-type conditions: Upgrade fact. lows with quality 65w driving beam lights and then do the fogs. Again, save the highs for last.
Hope this gets some of ya headed in the right direction but realize I'm not claiming to be an expert. I have done a lot of research and real world testing and I slept at a Holiday Inn last night

Serene -- check here for lotsa info and links to pics of the different Hella installs:

About the high beam + fogs mod . . . I found the links here
http://www.bfranker.badz28.com/fbody/guides.htm
but when I tried them, they were dead -- 404's ( scroll way down page to 'Electrical & lights' section )
It's been a while so I can't remember exactly which wire to cut and ground to the body but it requires pulling the relay box on the drivers side inner fender to access the wires. I'll try to take a look at mine to see but she's in storage and not easy to get to.
If anybody has a good link to a guide on this mod, please post it.

yes if anyone has a link to the mod please post it. I tried and the links were dead too.
I could just run a wire down from the bright lights to power a relay to turn the fogs on when the brights are on. that way relay box wouldnt have to come out and the switch would still function for the fogs.

Re: Are the Hella FF75 DRIVING Lights safe to use as low beams?
OK Serene, I just checked out the car and will try to walk ya through the mod. Note these are the colors on a 94 Camaro.
Pull the relay box cover on the front drivers side inner fender. Pull the Fog Lamp relay and note where terminal 5 is on the relay box. Underneath the box is a tab that pulls down from below to release the box from its bracket. Reach around under the hood adjuster bracket and relay box and pull this tab down enough to release the box and slide it toward the engine. Now push in the tabs along one side of the box that hold the bottom cover on the box. Start at one end and release one at a time by pushing the tab in and pulling down on the bottom cover. Once that is off, find the green wire that goes to terminal 5 on the box for the fog relay. A purple wire goes to term. 3, an orange to term. 4 and a yellow to term 2.
Once your absolutely sure you have the right green wire for the fog relay cut it a few inches from the relay box terminal. The part that comes out of the wiring loom is capped with an electrically insulated terminal and tucked back into the loom.
Attached a piece of wire (12-14awg) to the end that goes to terminal 5 and route this along the wiring loom that goes between the airbox or CAI and radiator. You'll need about 1.5 to 2 feet of wire. Ground this wire to the upper rad mount. My car had another wire grounded on a bolt there so I just crimped on a round terminal and attached there.
Make sure everything is electrically insulated and wont short out and tuck it back in place and check the lights. The fogs should now stay on when you switch on the headlights and turn on the brights. If they don't, make sure the fog lamp switch is on in the car
They should stay on with markers, lowbeams and highbeams.
Re-install the bottom cover. Slide the relay box back onto its bracket, replace the relay and cover.
Hope I explained it well enough as I don't have a digital back for my camera yet. Good luck. On a side note, the light on the fog light switch will still go out when you turn on the brights but the fogs will stay on.
