Perfect fit for a Tacoma.
There are 2 headlight bulb retaining clips in this packet that fit my 2013 Tacoma. Fits perfect, no modifications needed to the clips. Toyota dealers do not sell these clips alone, they must be ordered with the headlight housing. eBay has one for $50!!! AMZN beats them all.

Worked Like A Champ!
This kit had the retainer I needed, and I have a nice selection for future vehicles! I was looking for more crap to store in the garage, now I need a bigger tool box…
