Fast delivery, very well packaged, the seller is very responsive and professional, and helps you on all what you want thank you , not tested yet need to wait for harness relay , i will add additional review after installation
Very good size, the black boxes for input and output are the bulkiest parts. Again similar to the bi-xenon relay wire criticism, should have come with a plug with pigtails or a pair of connectors to use on the 2 plugs to the original car lighting circuit, however it uses 2 different size spades which are easy to source locally from auto stores.
CANBUS unit works well on Volvo with no DTC/errors. 4300K is a little yellow looking at day time, would have preferred 5000K if it was available, but at night, they have a factory HID look to them, so it's OK as is. Might pick up the higher colour temperature H1 for spares and to compare.
