Has anyone changed their backup lights. I believe my 2016 has 921 bulbs, not very bright. I need to get some bright LED lights. I don't think these need a resistor as there is no sensor for the backup lights. Was looking at Diode Dynamics, but $70 seems a bit much for a set up backup 921 bulbs. Tons on stuff on Amazon for around $20. Anyone have a bulb suggestion?
