So just real quick. Ive read some posts already but im still a bit unsure. One question. Do the Firebirds have any issues using any of those aftermarket sealed leds? Any issues with mounting them in the housings? And second if any of you do use them can you recommend me a brand?

Example

 

I would install halogens.

 

Are you recommending a Halogen Sealed-Beam, or a Modern Halogen H4 Composite-Bulb inside of a Glass Hella 5x7 Housing?



Hella 5x7 Glass H4 Housing shown above.

 

Plain old fashioned halogen sealed beams. Had a set on my 1972 Buick GS & worked fine for me.
