C4-SR Single Row LED Light Bar – IP69 (10"–50")

The Brightest Single Row on the Market — Guaranteed

The C4-SR takes everything that makes the C4-Series our brightest bar — 7W LEDs at 105 lumens per watt behind proven 4D projector optics — and packs it into a single row. It's the class-leading alternative for builds that want maximum output in a slimmer profile, with projection engineered for extreme high-speed race vehicles (140+ mph).

Rated for Race Abuse

Like its dual row sibling, the C4-SR is rated IP69 with upgraded weatherproof, shockproof, and impact protection for the toughest conditions on and off the road.

C4-SR FAQ

Single row vs. dual row — how do I choose?

Single row for slim mounting spots and cleaner looks; dual row (C4-Series) for maximum total output. Watt for watt they perform identically — the dual just fits more watts per inch.

C4-SR vs. SS-Series?

Both single row. The C4-SR runs stronger 7W LEDs, 4D optics, and IP69; the SS-Series is the slimmer, budget-friendlier option.
