Sealight LED Rear Tail/Brake/Turn Signal Bulbs - 88-98 Chevy/GMC OBS C/K Trucks

Direct replacement for the rear tail, brake, and turn signal bulb on 1988-1998 Chevy & GMC C/K1500/2500/3500 (and same-era Suburban/Blazer/Yukon) OBS trucks. One dual-filament LED bulb replaces the factory 3057/3155/3457/4157 bulb and covers tail, brake, and rear turn signal functions from a single socket.

Fits: rear tail light housing only (one bulb per side, driver + passenger).
Does not fit: the front turn signal. OBS trucks use a different, bayonet-base bulb (1157) up front — that is a separate, dedicated position and not this bulb.

30W / 3200LM per bulb, sold as a pair. Choose Red for factory-style red tail lens housings, or Amber Yellow for clear/smoked aftermarket tail lights that need a visibly amber turn signal through a clear lens.
