1974-1978 Firebird/Trans Am LED tail light Bulb Combo Kit

This includes led bulbs for all the lights that are in the 1974-78 Firebird/Trans Am tail light housings plus led side marker bulbs. The tail lights actually have 4 bulbs inside each housing plus a side marker bulbs (total of 10 bulbs per car), by getting this combo you can replace all the bulbs in your tail lights. LED bulbs are brighter than stock and have less electrical draw than the stock bulbs. You will also need to replace the flashers, you can add a pair (turn signals and emergency lights) to your order or use your own. Without the correct flasher the bulbs will flash really fast (hyper-flash) or not at all. The led flasher will cause them to work like normal. We also include install instructions with the kit that show how to swap bulbs, unlike newer Firebirds installation does not require removing tail lights from your car. 

We have 4 different bulb options for this kit:
 Holley Retrobright - Same size and appearance of the original except with the advantages of led lighting - lower current draw, brighter output and instant on. Uses Diode Dynamics HP3 bulbs for rear side marker bulbs. 2 year warranty
Diode Dynamics HP48 - brighter with more leds contained in the bulb plus a cleaner amber output and less electrical draw. Uses Diode Dynamics HP3 bulbs for rear side marker bulbs. 3 year warranty
 Diode Dynamics HP11 - Brighter output compared to the HP48. These bulbs have side and forward facing leds in the bulb for brighter output and more coverage. This option also includes brighter HP5 bulbs for rear side marker bulbs. 3 year warranty
Diode Dynamics XP80 - Brightest LED bulb available, big improvement over stock or other led bulbs. Similar design as the HP11 except with more leds per bulb for the brightest output of all the options. This option also includes brighter HP5 bulbs for rear side marker bulbs. 3 year warranty

Why are my turn signals too fast or don't work at all when I switch to LED bulbs?
LED bulbs have a lower resistance so older mechanical style flasher relays won't work with them. LED flashers are designed to function with LED bulbs solving turn signal problems like hyper(too fast) flashing or no flashing. The flashers we sell use a ground wire and include a polarity reverser. Unlike cheaper no load flashers, these will still make a low clicking noise so you know your turn signals are on. Most cars will not need the polarity reverser. Works best to try the flasher with the ground wire first, then if your turn signals flash very slow or not at all use the polarity reverser. Mostly cars with aftermarket or modified fuse boxes will need the polarity reverser. Either way you will have everything you need without waiting on more parts.
