Frequently Asked Questions
It’s designed to fit as an original-style replacement for Peterbilt 587 (2010–2016), Peterbilt 579 (2012–2021), and Kenworth T660 (2007–2017) applications. It’s built to match OE mounting and connection style for straightforward fitment. If your truck has been modified (aftermarket bumper, brackets, or wiring), verify mounting points and connector style before installation.
A 12V 55W halogen bulb comes pre-installed, so it’s ready to use out of the box. The bulb is replaceable, which makes future maintenance simple. For best performance, avoid touching the glass with bare fingers when servicing the bulb.
Disconnect power, remove the old lamp assembly from the mounting tab, unplug the connector, and install the new unit using the same mounting points. Plug in the OEM-style connector and test operation before fully securing everything. If the light doesn’t turn on, check the fuse, ground, and connector pins for corrosion or damage.
