The Peterson Dot XL lights are larger than other single-diode LED clearance/marker/mid-turn lighting options for heavy duty trailers, offering a surface area of 1-3/8" but still fit in standard 3/4" mounting holes. Dot XL lights are lensed in LumenX red or amber, and feature specially designed rubber grommets to assist mounting. All models have a 9-16 VDC operating range and are available with stripped wires or Defender-approved .180 bullet terminals. Options include a hardwired, two-wire design with 8" leads, as well as a three-wire version for auxiliary brake or turn functions.
