I recently purchased a bunch of super-white and red leds from autolumination.com
I replaced my dome light, maplights. reverse lights, rear turn signals, license plate lights, and trunklights. I went with red leds, 7440, for my rear turn signals(I have a sedan with gay altezzas so the turn signals were just a regular bulb that flashed really bright yellow). They turned out good and I like them, but I think I want to go with amber turn signals. As far as all the others, I went with the super-white leds, and I am very dissapointed. They all look purple and give off crappy amount of light. I took the the trunk light out and put it in my parking light on my headlights to compare it to my hyper-white non led bulb and the non led bulb looked whiter and was brighter. Now I am wondering if I should go and buy all hyper-white non led bulbs for my car, or did I just get crappy leds?
I have the led ones and I might as well not have lights at all, in my opinion they are worthless. Anyone with the regular hyper white bulbs have opinion on how well they work?
The hyper whites are fairly cosmetic, and it's true it makes it a little harder to see in the dark, but they look really cool, depending on the brand you obtain.
My 2003 Civic has all lights (except brake and signal lights) replaced with Polarg (Nissei) pure whites. They are the best pure white bulbs in my opinion, and they are a high quality JDM Japanese made product. Hope this helps.
My turn signals are off when not in use, they only turn on when I am turning, I think maybe because they are altezzas but I don't know. I don't know how true that is because I have a led light for my domelight and it fades out when I get out of my car and shut the door.
