Sealight SLJ4 LED Reverse/Backup Light Bulbs - 88-98 Chevy/GMC OBS C/K Trucks

Sealight SLJ4 — direct replacement for the rear reverse/backup light bulb on 1988-1998 Chevy & GMC C/K1500/2500/3500 (and same-era Suburban/Blazer/Yukon) OBS trucks. Wedge-base 1156 LED bulb, installed in the separate backup light socket in the tail light housing.

Fits: rear backup/reverse light socket only — this is a different socket than the tail/brake/turn bulb, so check your tail light housing to confirm you need this position.

30W / 3000LM per pair, 6500K White, sold as a pair. White only, since a backup light must read white by DOT requirement — no other color applies to this position. The SLJ4 is Sealight's higher-output performance tier over our standard reverse/backup bulb.
