do not do this unless your car headlight lens/capsule was designed for LED bulbs.

it just ends up being a while light blinding on coming drivers, while not projecting a good light on the road for you. Also with many LED bulbs you can lose your highbeams if you have a single bulb for both high and low beam.

Depending on the car, you can probably do it yourself. Mostly it just involves replacing the headlight assembly. One some cars it’s easy (older Toyotas and most Jeeps in particular, it’s super easy) but on others (Mazda) it’s a nightmare.

Yes. A mechanic can do this. We did it ourselves and bought the bulbs on Amazon. Get what you want and the mechanic will install for labor.

Who would do this? Any mechanic? Do I need to buy the parts first? Thanks!
