    In my 2017 prius we had to replace one headlight. The LED lights are hardwired in an assembly. The cost of a replacement assembly is $2700 [dealership price]. We had a local mechanic do it, he was able to find an aftermarket assembly for $2500.

    Removing the front bumper isn't very difficult - theres a plug under the drivers side to easily disconnect all of the wiring.

    I guess the aftermarket finally picked up the LED setup very cool . 2500 to light the road lawdy. On regular gen3 you undo screw in fender well like gen2 and ya tweak bumper cover out n forward n down allowing headlight to slide forward n out of car . I hope one is not doing this for bulbs.

    Remind me to never buy a Prius gen 4 and onwards. $2700 for one head lamp? That's beyond ludicrous

    Gen 3 ain't much better. A pair of sealed-beams used to be $20. Now the price for a pair of those effing sculptures rivals what we paid for our first car. Yeah, appreciate there's been inflation, but still...

    Is it that the entire housing is $2700 on gen 4 but you can just change the bulbs? Or it's all integrated and the entire unit must be replaced? The latter seems boneheaded and downright malicious.

    There are two headlight assemblies on a gen3. Most have halogen low beams and halogen high beams. Both bulbs can be replaced without removing the bumper cover.

    Trim 5 on gen3 uses an integrated led low beam and a replaceable halogen high. If the trim 5 led goes out you have to replace the whole headlight assembly. However you can remove the bumper cover screw in each wheel well allowing you to pull the bumper cover partial off. This allows access to two of the headlight assembly screws. If you were replacing one side only you could remove the bumper screw for just that side.

    On a gen2 I find it easier to do the partial cover removal than to blindly replace its bulbs. Some with small hands can do it blindly.

    Hey guys, I have the same issue. I think I must have installed the low beam halogen bulb incorrectly, and the socket melted, so now I need to replace the whole headlight.
    I’ll try to just loosen the bumper on one side since I only need to replace one headlight.
    Thanks a lot!

    You have to remove the plastic cover on top as well.
