When a single worn part costs $142.99 and a replacement device costs many times that, the answer is usually a part swap — but not always. This guide gives the decision criteria, using the parts listed for Headlight Ballast Driver Computer Control Module Unit for Me (3 variants) as the working example.
Headlight Ballast Driver Computer Control Module Unit for Me: Compatibility
The compatibility string on the listing names Headlight Ballast Driver Computer Control Module Unit for Me verbatim. Closely named models in the same family are the main source of wrong orders, so read the model printed on your device (usually on a sticker or in the device's app/settings page) and match it character for character — "Pro", "Plus", "Ultra", "XL" and revision suffixes all matter.
