Wires to short will have to add more which is a waste of money.

Couldn't get to stick to under dash,wire was broke on one,really couldn't do to much with wires being to short.if you got to spend extra on wire to make them long enough then spend the extra money on better lights.

The wire is very thin. I realize that thin wiring is probably needed but could at least give more outside coating to make it better for handling and installing outside. For the price, I expected better quality. I bought 2, one had short right away and not working.

One needs all the extra wires one can use. By adding more to your
wire hook ups to your set, adds more to your lab/kit. Have fun. Rob...

The comments about the wire are completely true, you will need to replace it but that kinda goes without saying since it is only like 3 inches long. Other than that, it seems to work fairly well for the price.

These would be better if they were able to accept a variety of gauged wires. I had trouble with 26 gauge, stranded wire making sufficient contact with the  terminals.

This product is cheep with lots of wire's that are very short and brackets that are hard to mount. I had to order two sets just to get enough wiring  to make them work in the vehicle locations is had mounted them . the switch boxes go out and sometimes products come with out wires or switch boxes please check your. All though they will sent you replacement but will not sell just wires by themselves for extensions. you have to purchases another set . I removed them and bought a Traffic Directional LED light stick which is brighter and more reliable. They also turn yellowish brown in rain.

A bit difficult to install if you have a bunch of wires in the box.

Does not work very well with 16 awg wire. Wire does not fit unless you take off the color coded ring.

Fan wiring to short by 3 inches, had to get more wire by taking short cut out of wiring harness. Unit not as sealed as factory and the fan blades not built nearly as strong as the old one.

The metal on the backside to connect the wires is way too small.  Even using 16-22 push connections doesn't work well.  The pictures don't emphasize how tiny these connections are.  You can find better.

While it's a good idea the brackets could be a lot bigger to fit larger tubes. It would also be nice if instructions for converting a 2 wire setup to the 3 wires on the light.

If you need extensions you will need these they come is various sizes and can be pricy if you need more then a few. If you handy buy the 1 foot size cut them in half and make you own in the lengths you need with wire from the local hardware store.

Cords are too short. I understand the safety thought on the short strings but they are not long enough to do anything.

Wiring is too short to reach from where the sensor sockets into the exhaust to the wiring connection without running against the engine

Disappointed with the purchase! If you are thinking of passing wires through them, you are better of with buying something else.
