Questions about United Pacific 31150
Can 31150 replace both low- and high-beam lamps?
Part 31150 provides low beam only. It does not supply a high-beam pattern. Keep a compatible separate high-beam lamp in the truck’s lighting system.

No. The main lamp uses a matching headlight harness, but the amber position-light bar requires an additional electrical connection. Confirm the correct circuit before fitting it.
