Recently just installed these LED side marker lights by myself. LED bulbs draw such little amperage that it is possible to run these lights off any other circuit without blowing fuses or overheating wires. I like the fact it is a sealed unit. Overall, it is an improvement on my car which did not have any side markers for turning. It took me 30 minutes per side including drilling and running wires, and soldering. Quite fit on my Ram. Came out pretty good. Bright and should last a long time.
