I read somewhere recently that a guy had developed a relay mechanism that hooked up to your headlights. The way it was stated, the conductivity of the aging wires kept the full amount of power from getting to the headlights. The guy wired up a relay system that made sure that the headlights were always getting full (seemingly uninterrupted) power, thereby getting better light from the headlights, but it was for a motorcycle headlight. With all the complaining I've been reading on here recently about the alleged ineffectiveness of the 1G/3G headlights, I was just wondering if anyone had heard of this setup (or something like it) and if it really worked.

I suppose that makes sense, a relay does allow for more power to go to the lights, i wired up a relay for the fuel pump on my carbed car....

Seems like it makes more sense to wire a relay using the head light switch to a set fo 4" or 5" rally lights.... that way you can out shine those big trucks and suv's.

My buddy Matt recently did something like this. He used the original headlight power wires to turn on 30amp Bosch relays (one for left and right low beam, one for left and right high beam), and ran power for the headlights directly from the battery. Grounded to the stock hedalight locations, and he used 'overkill' gauge wire to hook everything up. This lets him get 13.x+ volts from the battery instead of the 12v from the switch, the lights don't dim at lower RPM's or fluctuate when the turn signals are on. He's said that the results are VERY nice.

Sounds like a better alternative than those ugly blue lights i used to have on my car. I might have to try this.

Yea, I don't like the wal-mart blue add on lights either. I just have some white bulbs in my car, but this relay sounds like it might be worth my looking in to. Good thinkin' TAAGMAN!

Im still in the middle of trying the 9007 conversion, after that i will probably get a Upgrade Harness like ur talking about, u can buy them for like $30 bucks i forgot where exactly but some googling should find em, they make them for the bulb style all u have to do is supply power and ground

I have Silverstars in there and i like them alot, they whiter than the stock lights and i think there about 10-15watts more than stock

Everybody whos done the 9007 conversion says it like driving with the High beams on before with the low beams on now, i just havnet had time

I have Hella lamps in my car..... they are bright.

I did the relay trick a while ago, makes a really noticeable difference.

That being said, switching to 85w low/110w high's made a pretty big difference, too!!!

PS.... Yes... I know that's illegal.
No.... I don't care.

Edit: If I have time and can figure out how to, I'll post a diagram for you guys.

Headlight high beam wire to new high beam relay control input. Other end of control input to ground. Large gauge wire (10 is fine) from battery to fuse to switch of relay. Other switch of relay to high beam wire of headlight (you'll have to just cut the harness). Ground can stay as before. Both headlights can come off this relay.

Low beam....another relay, Take the large battery wire from the first relay and wire it to the switch relay of the 2nd relay. Other than that, wiring is the same. Size the fuse for the wire size and derate by 50%.

If you have normal headlights, you can wire it so that both hi and low come on when you put on your highs. I do this plus add whatever driving and fog lights I have on the vehicle. I had a pickup with a set of good driving lights, good fog lights and the hi/lo all on when I put the highs on. It became daylight.

Do fix up that diagram when you can, Jonesy. I'm a work from picture kind'a guy. Thanks.

[s.wilson]

Yea, the written explination kinda makes sense but i'd really like to see a diagram, because i'm a visual learner too. That way it's that much harder to screw up.

[bigk3000]

thats really easy to make... you just need a simple bosche 12 volt relay.. you can get themn for liek 50cents..



pin 30- would be yout thicker 12 volt positive straight form the battery ( with a fuse of course)

pin 85 - input - would be your original 12 volt switched source taht used to power the lights..

pin 86- negative / ground

pin 87- output - 12v positive to the head lights

Wow, that could explain why my CRX headlights were so bad....9004's are only rated at 700(low)/1200(high) lumens. 9007's still kind of suck at 1000/1350, but then again I've been spoiled by the 9005 (1700 lumen) bulbs in the lows in my '91 hatch .

For everything except the 9005 (since they don't make it ), I'd go with Sylvania Xtravision bulbs. The filament is about as overdriven as Silverstars, except without the output-reducing blue coating. That said, I have a pair of left-over Silverstars from my 1G project that I'd be more than willing to sell .

[DarkHand]

If you have normal headlights, you can wire it so that both hi and low come on when you put on your highs.

That's a really good idea actually.
Although it can't be good for the life of the bulbs.

I found this diagram on another site of what is described here.



Hope it helps
