Sealight S1 LED Headlight Bulbs (9005/9006 Combo) - Composite Housing Only - 88-98 Chevy/GMC OBS C/K Trucks

9005 (high beam) + 9006 (low beam) LED bulb set, 2 pairs — for aftermarket composite headlight housings only.

Important fitment note: factory 1988-1998 OBS headlights are sealed-beam units with no replaceable bulb, so this bulb does not fit a stock headlight. It is designed for the aftermarket composite/reflector housings we sell for this platform (ANZO USA, ANZO USA Crystal, Xtune, and Spyder Signature Series headlights), which use 9006 for low beam and 9005 for high beam. If you're running factory sealed-beam headlights, this bulb has nowhere to install.

Sealight S1 tier — 60W / 6500K White, 14,000 total lumens (3,500 per bulb), IP67 rated, passive fanless cooling. Sold as 2 pairs (4 bulbs total — enough for both sides, high and low beam).
