Product Overview

Nine SMD 2535 diodes on the 4 inch round platform, for operators who find the 7LED version adequate on tarmac but want more rear output on dusty or spray-heavy routes. Same grommet aperture, same welded seal, more light.

Key Benefits

Two extra diodes over the 7LED lamp without changing the aperture
Grommet mount keeps installation identical to existing 4 inch stock
Stop, tail and turn from one sealed housing
12V, 24V and 10~30V versions available

Who It Is For

Fleet buyers upgrading rear lamp output across an existing trailer population.

Problems It Solves

Rear signals wash out in dust and spray behind bulk vehicles
Output upgrades usually mean a different lamp size and new panel work
Mixed lamp sizes across a fleet complicate spares

Application Scenarios

Bulk tippers and tankers running in dust and spray
Trailers used on unlit rural routes
Fleets upgrading rear output without panel modification
