Bought these blue LED
marker lights and used them as underglow. I’m pleased with my purchase, the color is great, durable, I'm totally impressed. the lights were easy to install (as long as you have experience working with wiring). I liked that the kit included heat shrink splices, which made the installation much more reliable than just the old blue trailer light connections. I trust that now that I have LED lights, I won’t have to worry about replacing corroded bulbs.
