Yes, it was tough to change to whipless but it also meant I could benefit from the lighting without huge whips behind me. It’s a personal choice but these worked out great. Highly visible and bright and the install was pretty straightforward and simple. You get everything you need with the kit. They look good and seem to be holding up durability wise very well. Overall, I may not stay with them over time but it won’t be because of quality or function. It’ll be because I want to see the long whips again behind me.

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…
