We don't really have a thread for our car that I was able to find that addressed specifically what works in the Roadster. There are one or two posts including one of mine asking questions but while looking for those answers I figured I might post what I've found and/or tried so far.

I have replaced my fog lights temporarily with Nokya H8 Hyper Yellow bulbs:

I would give these a 7/10. They look good, but they really aren't 2500k temperature. I would say its more around 3000k-3500k. They are about identical in brightness to the factory-installed bulbs. I will likely eventually get HIDs to put in here, probably the Morimoto set or a set from DDM.

I also took a chance and tried these LED bulbs out to replace my city/parking lights:

These didn't have a temp rating, but they are about 6000k - blueish-white. They don't quite match the factory HIDs, obviously. They are roughly the same brightness as the little factory bulbs they replaced, but the 6000k causes them to not seem as bright. These won't stay in for long because I'm going for "WHITE", but if someone has 6000k HIDs these would look fantastic, especially for the price. No errors yet, and they are canbus bulbs so there shouldn't ever be any.

I'm going to be getting some bulbs to stick in my reverse lights next. I'm trying to decide on just the right ones. There are some sets that use a 5w Cree 450 lumen projector LED that are very tempting. Those would also likely work in the city/parking lights that I just tried (wedge bulb type). Maybe I'll get a couple sets

I encourage you guys to use this thread if you have any lighting mods you've done, what you used, if you had issues, etc.

If you have any questions post here. I'll eventually try to post a list of specifically the bulb sockets, wattage, and actual space/clearance in the lamp as some of those LED tower bulbs are fairly tall.

 

Also I'm interested if anyone has found any LED bulbs for their turn signals that totally vanish in the factory-clear (non amber) lenses.

 

Well, the cheap Amazon bulbs are burning themselves out :| Back to the drawing board!

 

I bought Stealth bulbs off the bay but they are not LED. They look great, like silver in front of the silver reflector, until flashing and they appear amber. No egg yoke appearance at all.
