These are not 4000k as advertised. More like 5100k.

Used the sealed light for my boat trailer. Had to use my grinder to make a notch, between bolt holes on light mount. Works well. No more taking off cover to reseat the bulb.

Only one tail light has the license plate illumination. Ground wire must be connected to light stud. I have been installing lights on trailersfor 20 years,these are the worst i haveever used.

Left (license plate) light main led array failed after 6 months. Was never submerged. It is not waterproof. Insulation is a joke. Drained them and now led's are going out.

Only came with 4 nuts. Just cheaply made all around. Warning to other consumers. Was told to contact seller.

Lights havent even laster 4 months and one od them is already failing. Supposed to have one year warranty. Crapped out in 6 months.
