Sealight L2 LED Tail/Brake/Turn Signal Bulbs (Amber) - 88-98 Chevy/GMC OBS C/K Trucks

Sealight L2 — 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 3157/3156 LED bulb replaces the factory 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.

9W / 1500LM per bulb, sold as a pair. Amber only — for clear/smoked aftermarket tail lights that need a visibly amber turn signal through a clear lens. The L2 is Sealight's efficiency-focused amber tier; if you need red tail/brake output, see our SLJ6 red bulb, or one of our white+amber combo kits for a matched pair-of-pairs.
