Bulb Replacement Question
Replacing my rear stop/ tail/ turn signal bulbs.
Just looking for stock replacements.
Local parts joint has Sylvania & Westinghouse with "LL', "BP", "NH", & "ST" after the 3057 & 2057 numbers.
I know "LL" means Longlife....but what do the others mean? And which ones are best. Don't wanna melt any wires or housings.
Thanks!

I know the Silver Stars use the ST suffix but not sure what it stands for; possible a trade mark? ST is about 30% brighter than stock and SU is about 40% brigter.
I think NH is the Night Hawk trademark.
NA is natural amber for the turn signal amber bulbs.
The rear lights are easy to change so I wouldn't pay over the odds for a replacement. You won't melt anything if you use 2057/3057 bulbs. The stock bulb is a 3057 which is slightly brighter than a 2057 so I'd stick with a 3057 so you don't have different light levels between the 4 clusters.

I thought "ST" might be "Stop Turn" signal bulbs.
