HID to LED conversion
So, right before Kinja all went to shit, some of you may remember that I started to convert the HID bulbs in my 08 IS250 to LEDs.
why? Well, 2 part reason. 1 part: HIDs lose strength as they get old. Nothing you can really do. So my low beams were very weak. It got to the point where my fog lights (which, admitingly, were LED already) were far brighter and accounted for like 70% of my forward lighting
The main reason however, was that my car had burnt out on of the ballasts for the HID on the passenger side, so i didnt have a low beam on that side. And then the fog-light went out, so I had NO lights on that side of the car.
So, step one. Remove bumper and fix fog. Turned out water got into the connection and corroded it to hell and back. One new bulb and a new pigtail, and that fixed that!
After, I took the headlights inside as I wanted to crack them open to polish up the inside (corrosion) and do a little something to change the look. I took the chrome liner out and sprayed it with black plastidip. I didnt spray the reflector, so the lights are still as bright. But it Makes the car look FAR new then a 12 year old machine.
After the plastidip, I bypassed the ballast and the ignitor, and just plugged in the new bulb.
and my god is it bright now. the cut-off is JUSt light the factory lights, so i'm not blinding drivers with it (car was on jackstands, hence the apparent glare)
Over all, it was a bit of a pain in the ass as I took the headlight apart to clean up corrosion and paint the inside, but I'm reasonably happy with how it came out. I'll have to clean up the passenger side lense again later, and re-seal it (my bad) but over all, a fun little project and awesome results.

Honestly, I forgot you owned a car.

Looks good! I know I'm looking at converting my halogens to HID or LED, just trying to find a solution that doesn't blind everyone. But the 2 candles currently lighting my way aren't doing the trick.
@dtg11 go LED for sure. much much easier to do.
also, modern LEDs are much ebtter made and have a beam pattern very similar to halogens.
my advice: get a bulb that has as FEW LED elements as possible. The amazon ones with like 40 little bulbs have terrible dispersion and will blind others. The bulbs with one giant LED each side work FAR better

@peter_black Noted! I appreciate the advice. I'm hoping to update all my lighting to LED like I did on my G37, headlights excluded. So far, I just have interior and brake lights, but it's easy enough to do piece by piece.

@peter_black don't you need projectors too?
@s65 the HID were already projectors, I just changed the bulb

@dtg11 I got the Ebay LED bulbs for my wifes forester, and Ebay projector lenses. It took some customizing but it's perfect now and it cost me $100

Headlights weren't a big deal to get apart? They weren't glued or plastic welded at the junctions?

@vincentmalamute it was glued all the way around. But 15 minutes in the oven at 205f made it soft enough to just peel apart. It really was pretty easy.
I screwed up the resealing on the passenegr side though. I got a bunch of sand and what not in the glue channel and tried to scoop it out with a heat gun and a screw driver. I removed too much glue and now it dont seal up. Ah well, c'est la vie.

@peter_black What glue did you use to glue it back up? ah, reading all of your response says you just heated the glue back up with a heat gun?
Were you doing this project on the beach?
@vincentmalamute just the same glue that was in the thing already. To put it back together, I stuck the whole thing back in the over (again, 205 for 15 min) to soften it and the glue on the lense, and just pressed them back together.
no, it was just a bunch of small rocks and what not that some how made their way into the headlight. and when i popped the lense, they just fell in. Annoying to say the least. But its winter now in canada, so IF i take it apart again, it will be in the spring time.
Are the LEDs better than just replacing the HID capsule?
@ibrad significantly. I bypas the ballast, the ignitor, and clean up the wiring.
also much cooler and less susceptible to voltage spikes.
