Thread: headlights not turning on

Lol, all these posts are from like 8 years ago. Still can't believe I still have my GTP ;D I came across this post when experiencing similar problems. The above poster's suggestion WAS correct. I also have HIDs. & they would intermittently come when while testing them in my garage & looking at the wall to see the reflection of whether or not they would come on. So, I removed the headlight housings & tried a few old school 9007 bulbs that I have in storage just in case. Sure enough, they lit right up.

Next, I wanted to inspect the HID ballast, relay, & bulb connections. All seemed visibly okay. One of the two connections to the ballast looked like it had some corrosion on the pins. I took a small file & cleaned that sh*t off & inspected everything else. I also cleaned the two ground connections (I just use the center-most bolt of two 10mm headlight bolts on each headlight to ground them - that's a pretty good place to ground them as long as you sand a small shiny spot of the chassis under the 10mm bolt washer).

I put the HIDs back in & they seem to work fine. Still experiencing occasionally the passenger side one not coming on but if I manually flip the headlight switch off & then on again they both will usually come right back on. It might be the ballast going out. I just looked on eBay. A replacement Zenex 35w ballast is like $27 w/ free shipping. I've had the same kit in since I think 2010. Zenex out of Florida makes SUPER good quality stuff & they always stand behind their products & their warranty. I have both Zenex headlights & fog lights. 6000K for both. They're awesome.

My mechanic at work (I work at a car dealership) recommended getting LED headlights. My HID problem, turns out it wasn't the ballast. I'm almost certain it's the relay after jiggling the relay wires & the lights would then come on & off as I wiggled them. I carefully took apart the relay box & the circuit board on the inside just slides right out for inspection. On the backside of it in the bottom corner, there's a ton of corrosion. I tried using MAF cleaner & a soft brush & cleaned it up best I could. Works okay for now. The driver's side bulb comes on 100% of the time but the passenger one sometimes comes on, sometimes it doesn't. I have to return that new $27 ballast I bought & I already ordered a new $8 relay wiring harness off eBay. My HIDs are 6000K. That color's called diamond white. They look nice. I, also, do not like the blue tinted headlights. I've seen pics of where they JUST start to leave my color range & enter the light blue tint. There are pics around the web of another fellow GTP owner's black GTP with that color range HIDs. He's got the BOOST GETS YOU LAID decals on the front & the same silver upper & lower grille kit that I have. Nice wheels, too. His car looks awesome!! I'm guessing those are 7000K HIDs.

This is what mine looks like.
