I worked with this company for 3 months to get the LED bulbs to work in my 2022 RAM. After many phone calls to support and a litany of emails they said I needed to had a module for my RAM which after waiting a month never came. I returned the bulbs and asked for my money back. Their response was that they do not refund for "used" bulbs. They won't work in my 2022 RAM (they turn off) and they wont refund my $300.
