Adding modern headlights and LED lighting to older units can REALLY help update the look, as well as visibility to others. This is what I’ve done to the SportChassis so far. Be sure to use high-quality components so you are not replacing offshore parts every month. Quality counts, as this is a high-vibration environment with unstable voltages.

Philips & Sylvania LED bulbs are my weapon of choice for the basics, and usually great pricing from my Amazon affiliates link compared to local vendors. Grote and Truck-Lite dominate the replacement lens and have some great options pending your budget and styling.

**NOTE: These are all the connectors my 2006 model year uses, or you can hardwire and cut off any connectors you do not like. Later model years and M2’s other than SportChassis may come with different plugs/connectors for things like brake lights, pull your existing light and confirm plug-ends as required.
