Does anyone know the standard bulb type of the three bulb types in our tail lamp assys?

Not GM P/Ns-- I'm looking for types so that I can cross-ref for brighter bulbs.

TIA!

OK. Disregard- I moved to brighter overhead light so i could read the damned things...

1155 (Reverse)

1155A (Turn)

1157 (Tail / Brake)

So there.

Anyone know of a good one-stop source for brighter lamps?

I just noticed that there's no 1157 halogen or Silverstar...I wonder how bright the amber Silverstar (1157AST) is...

Update-

Halogens weren't going to work- WAY too hot. But I did find some direct-from-Japan superbright 35/5W 1157 bulbs on the Interwebby thingmie that seem to work pretty damned well.

Problem solved.

Why not use 2357's in place of the 1157's. My mid 80's Suburban benefitted from this immensely as the gmc taillamps were rather dim. :cool
Amber 2357's really woke up the bright brake lamps, and if you think they're too hot, try 2057's.
