ZKFAR 2 PCS H4 Car Led Light Bulb Retainers, 0.4In x 0.6In Nylon Fiber Durable Light Bulb Adapter Sockets, Universal Waterproof Vehicle Lights Buckle Holder Accessories for SUV Truck (Black)

This product is shown with "red" rubber waterproofing rings in order to install in existing sockets. I have ordered "two" sets of these with no red rubber rings included.

These were constructed well and fit my "old" FJ Cruiser Sylvania light bulbs, however, it didn't work for the newer LED bulbs I got. The base of that was larger in diameter and so these didn't fit.I'm not docking a star, though since they are quite thick (the material) and seem super durable. I just didn't measure my LED bulbs correctly.

The item I purchased was for an H4 low beam and should have been for an H7 High Beam. Obviously, the retainer clip didn't fit. However, the clips appeared to be well made and the tabs that go into low beam headlight assembly appear to match if I had paid better attention and purchased the correct retainer clip for the high beam. Sorry that I cannot comment on how clip would have performed or how easy/difficult installation would have been.

This does not fit 04 mustang gt

Despite Amazon's "Confirmed Fit," these do not fit any of the lights in my truck. They do, however, match the description, and appear to be well-made and of quality material.If you were considering these for use with a 9005 or 9006 lamp, look elsewhere -- they will not fit (Photos show comparison with (much smaller) 9005 ring). If you're using H4 lamps, they might be good.

Este producto es malo, no venden H4.El modelo que me llego es más bien para un H11, demasiado pequeño
