also, i notice the ones i am looking at are halogen. is there any special modifications i need to do to my wiring or anything else, to run the halogen bulbs ?
thanks guys. leonard | | | | | Joined: Nov 2002 Posts: 1,002 Shop Shark | | Shop Shark Joined: Nov 2002 Posts: 1,002 | Without knowing what the wattage difference is between the incandescent(?) you are replacing and the Halogens, it's hard to say. I think it's safe to say that the Halogens will draw more current, how much I didn't find in my quick search. There are other factors to be considered wire gage, and lenght of wire. Here is an article from Hiperformance Chevy; http://www.chevyhiperformance.com/howto/4417/index.htmlThe article has some good thinking behind it. There have also been some posts on using Bosch relays here. I'd do a search for them. IF you are also going to be adding some fog lights or driving lights it would be good to learn how to use the relays. It might also be a good time to check what your total current draw is, and if you might be exceeding the amperage on your alternator. I found this listing in my search, the numbers look a little high but,,,, - Typical current draw; http://townsendsautomotive.com/shared/content/Library/encyclopedia/ch11/11fig16.htmlWhen I was rallying some of the competitors had enough candle power that with all the lights on they were slowly draining the battery, and that was with a 95 amp alternator.

im gonna do more research myself, and thanks again for your time.

I have style with the plastic housing, they came with an H4 halogen bulb, but I upgraded to Sylvania Silver Star bulbs. It was essentially a plug and play operation. I did not add any extra relays, they run on the regular harness. Haven't had any problems with them at all, the wiring doesn't even get warm.

That is why we began retrofitting our trucks about 25 years ago. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Yes there is a noticeable difference. | | | | | Joined: Aug 2007 Posts: 1,082 Shop Shark | | Shop Shark Joined: Aug 2007 Posts: 1,082 | | | | | | Joined: Mar 2009 Posts: 15 New Guy | | New Guy Joined: Mar 2009 Posts: 15 | I used the same seller & lights when I up- graded the lighting on my '73 Camaro. I also added some relays to my lighting cicuit jus cuz I already them. I also plan on doing this to my truck when the time comes- excellent and cheap up-grade. | | | | | Joined: Aug 2007 Posts: 1,082 Shop Shark | | Shop Shark Joined: Aug 2007 Posts: 1,082 | ordered them today. should have them in one week. when i get them installed, i will post pics.

leonard Cool...I haven't had a chance to look at my '55 light buckets yet, but I had to cut away some material when I installed them on my Camaro. The backside of the light assembly is close to 3" in dia. and I had to hog out my stock ones to make things fit. | | | | | Joined: Aug 2007 Posts: 1,082 Shop Shark | | Shop Shark Joined: Aug 2007 Posts: 1,082 | ordered them today. should have them in one week. when i get them installed, i will post pics.

Thanks for the help.

leonard | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | They would work if you could find a 6 volt equivalent to the H4 bulb fitment.
Bill Burmeister | | | | | Joined: Aug 2007 Posts: 1,082 Shop Shark | | Shop Shark Joined: Aug 2007 Posts: 1,082 | got the tri-bar's in today, have them installed. still have to wait for the weekend to aim them and take pics. plugged right in to factory wiring. had to trim the circle opening on the bucket that goes on the back of the headlight. also had to modify that same bucket on the passengers side where the 3 notch openings are, to get the headlight timed correctly where it say "top". cut 3 notches where i needed them. overall an easy install. will post pics this weekend.
