Compact, Sealed LED Marker/Clearance Solution

The Truck-Lite 33050R is a 33 Series, 12V round LED marker/clearance lamp engineered for tight mounting locations and long service life. A single red diode sits behind a durable polycarbonate lens, with electronics completely encapsulated in epoxy to resist moisture and corrosion. The lamp installs with the included black rubber grommet and hardwired pigtail using .180 in bullet terminals for a secure connection. With a 0.75 in lens diameter and a matching 0.75 in mounting hole, it’s an efficient retrofit for existing 3/4 in openings.

Installation Fit and Kit Components

This kit includes the 33250R lamp and 33700 rubber grommet to streamline ordering and installation. The grommet mount supports typical panel thicknesses of 0.125–0.250 in, while flange applications support 0.040–0.250 in. Solid-state LED technology provides low current draw, reducing electrical load on the alternator and battery. The compact form factor and grommet design simplify placement on trailers, vocational trucks, and other heavy-duty equipment where space is limited.

Compliance and Durability

The 33050R meets DOT, FMVSS 108, and CMVSS 108 requirements and carries an SAE P2 marker/clearance classification. Its sealed construction and impact-resistant lens help the lamp withstand vibration, road spray, and debris. Designed for both new builds and retrofit programs, this light delivers reliable, compliant visibility while helping lower maintenance and replacement frequency.
