This Peterson teardrop light gives your trailer a clean, classic look while keeping it visible at night. The 5-3/8" long x 1-13/16" tall design uses an amber lens over a bright incandescent bulb to serve as either a clearance or side marker light. The built-in reflex reflector means you don’t need an extra reflector plate. It’s P2 rated for proper light spread and is fully DOT compliant, so you get both function and peace of mind in one unit.
Wet conditions are no problem here. The housing and lens are sonically sealed together to create a single waterproof piece that’s submersible. That keeps water out and protects the bulb and wiring even when the trailer is exposed to rain or water spray. It’s a dependable pick for anyone who wants lighting that holds up through tough weather or washdowns without fogging or shorting out.
Installing this light is straightforward thanks to its single-wire design that grounds through the mounting flange. You just connect the +12V lead and secure the housing with two #6-18 x 3/4" screws (included). Because it uses the metal flange for ground, a bare metal contact point ensures a solid connection every time. The surface-mount style lays flat against the trailer body and only requires a small hole for the wire pass-through.
The wedge-style teardrop shape makes this light ideal where space is limited or when you want something that blends in instead of sticking out. At only 1-1/2" thick, it sits close to the surface and adds visibility without snagging on anything. The 3-1/8" mounting hole spacing makes it easy to replace older lights without modifying your trailer’s setup.
Peterson’s incandescent build provides consistent brightness that’s easy to see from straight on—perfect for marking trailer width or corners. Designed for 12V DC systems, it’s ready to wire up and go, keeping your trailer visible trip after trip with simple, proven lighting technology.

I have contacted the manufacturer and they have confirmed that they measure the mounting holes with a caliper and the diameter of the head cannot be larger than 0.25 inches, but you can go longer than the 0.75 inches length of the screws provided. The current screw specs are 6-18 x 0.75 Type A., Type 1 cross recessed fillister head tapping steel screws with black oxide coating.
