The Peterson LED line of tunnel lights with the new 274 series features a 2-in. round, grommet-mounted accessory light for trucks and trailers. It operates from 8 to 16 volts and comes in amber or red. Designed for accessory or off-road use only, the tunnel light fits standard 2-in. rubber grommets. It comes with 0.18-in. bullet plugs, which can be removed for hard-wire connection to vehicle harnesses. The non-polarized design allows connection of the hot wire to either lead.
