At first I was impressed with PrecisionLED's marketing photographically measuring interior lighting improvements and emphasizing "LED bulbs that are carefully selected for your specific model". I did my own research and found competing bulbs for half the price but I decided it was best to leave it up to PrecisionLED to be certain I had the right parts and dome and map LEDs that matched one another (CAN bus, luminosity, color temperature, dimensions, bulb type).
Unfortunately, the LEDs that were sent to me did not match what was in the product photos that I was expecting to receive: They were the wrong dimensions, and wrong bulb type. They let me do an exchange. It still didn't fit right but I made it work.
The actual lighting was a huge improvement! But, unfortunately, my dome light has already burnt out after a year and a half (5000 miles).
