For the price these ballasts are amazing, super easy to plug in and great quality feel of the body and wires. Canbus/capacitor modules built in feel a little cheap but they work as intended so far no issues on my truck with errors and bo flickering. I bought two sets of these to run high and low beam my only complaint so far are pretty minor, the supplied double sided tape is junk, the plug leads are short with the inline modules to easily mount out of the way, lastly the second set I have on the high beam is a lot slower to power up but that may just be how my vehicles electrical system is wanting to function. Otherwise amazing product
