The lights work great but the instructions are in a foreign language Japanese does not helpHaving a hard time getting the unit to stick to the door.They're some what of a pain trying to set up. You will need patience trying to get the magnet to line up. Well at least if you have a Dodge Ram, but end result is super cool I like it and the light is bright not mad I got itThey went on fine and worked OK. Then the6vfell off. Can't get then to stick again.installed these on a Nissan Np300. If it wasn't for my mother that watched the thing fall from the door, I would have lose it. Use other kind of glue or a real 3M tape.The magnets Included are too small and needs modification or additional items to reach the height needed to activate the lights.Very difficult to get mange to sensor readers to align in the install process. Otherwise great product. Change the batteries a TONNN BECAUSE OF THE SENSOR NOT TURNING OFF.At least a stronger magnet will make it work. The supplied magnets must be very close to the unit as installed..I brought this for my boyfriends ct5 Cadillac and it was perfect! Install was easy! The 3M tape has a strong hold!
