Doing the Sport Light swap on your 2002 truck is easy.
Here's my writeup on the Dodge Ram Sport Headlight Conversion for earlier trucks - just ignore the parts about trimming your headlight buckets because yours already has the needed clearance. My writeup includes a link to the suvlights.com Dodge Ram (Sport Headlights) Conversion Harness w/4 relays.
The Sport Light conversion with relays made a HUGE improvement in light for night driving!
Charles,
I am about to start on this conversion and want to make sure I am doing this correctly. Get the harness you state above and get some Sport lights from the salvage yard or order them on internet. I am correct here?
