4 inch grommet-mount round lamp, SMD 2535 7 LED
The baseline 4 inch round lamp of the range: seven SMD 2535 diodes behind an engineered lens, dropped into a rubber grommet so the lamp floats clear of panel vibration. It covers stop, tail and turn on a 4 inch aperture that most trailer builders already cut.
Trailer builders and parts distributors who move 4 inch round lamps in volume and want the plain, lowest-diode-count version.
PC lens and housing, ultrasonically welded into one permanent waterproof body. Housing material and finish vary by model and are listed in the specification table.

Hardware production, laser marking, heat diffuser assembly, light source welding and thermal grease application run on our own semi-automatic lines. Lens installation, shell assembly, ring fixing and spring insertion follow in product assembly.
Grommet-mount lamps are aged on the test rack and checked for output and colour before packing; each batch is 100% inspected before delivery.
Lowest diode count in the 4 inch family — step up to the 9LED or 14LED versions for more output, or the F3 Piranha versions for the sealed 3-pin plug.
Fit the grommet into the 4 inch aperture first, then press the lamp home
Use the matching plug rather than cutting into the lamp lead
