Probably the single best upgrade on any car, best bang for the buck, that you can possibly buy. Imagine walking up to your car at night, hitting the unlock button, and the watching the entire interior become lit up light daytime in a beautiful crispy white hue. The great thing is that you can easily achieve that with 1 to 3 bulbs, depending on the configuration of your interior lights. Some Dome lights use 2 simple glass bulbs which cast a very dim, minimal amount of yellowish light, while others only contain 1 single "festoon" type bulb to accomplish this. Simply swapping those stock bulbs out for our high power LED units will no doubt put a smile on your face when you see your car light up for the first time at night. Its fast, easy, and affordable for just about anyone with a car that actually wants to be able to see their interior at night!
