License plate bulbs are used to illuminate the rear license plate on your vehicle. From the factory, the bulbs are incandescent, lighting up in a yellowish color. Newer luxury cars use LED modules to illuminate the license plate with modern, cool white light. Available for all 1974-78 Firebirds.By changing your license plate bulbs to LED, you can easily add this luxury look to your vehicle! The installation is 100% plug-and-play and dosn't require resistors or new flasher, just replace your factory bulb. Includes (2) Cool White 6K bulbs.
There are three different bulbs available, all have 3 year warranty:
HP3 - Brighter than stock, also has a white light instead of a yellowish stock color.
HP5 - Same advantage as the HP3, except much brighter than stock and has a better diffuser for more even forward and side lighting.
OSRAM - Lenses on the tip of each bulb help distribute light evenly through the face of the bulb. The Osram produces much more "forward" light.
