WOWLED High-end Wiring Harness Kit, LED Light Bar Wiring Harness Kit for Off Road Lights LED Light Bar with 12V 40A Relay On Off Switch(2 Lead) : desertcart.co.uk: Electronics & Photo

Review: Good harness but some cables are to short - It’s a good harness, BUT the power cables and ground cables definitely could be longer, or at least longer cable to cut to desired length then crimp on the connections, It’s good for what your pay for though, Install will vary on what your doing, again cable lengths to be longer would be a big help
Review: Goof quality - I did end up cutting a fair bit out of this. I fitted an isolaton switch so their setup didn't fit mine, exactly. Also every vehicle is different in size and battery pacement. I could have made up my own harness, BUT, it's a very good quality bit of kit that has been in place for over a year with no issues.

## Questions & Answers

**Q: Are they road legal?**
A: Mine are set-up as Reversing Lights and in that case the Answer is Yes. but no idea if you wanted to use them facing forwards as Running Lights.

**Q: Lights won’t stay on. What’s wrong? I’ve wired up as per instructions but the rocker switch on turns on when held down.**
A: It sounds like a faulty switch if it only works if you have to keep it pushed on OR your switch is not seated properly in your allocated slot

**Q: 240w requires 20amp cable? The cable deliver is 16awg rated at 10. Is the 240w harness suitable for 20amp?**
A: Yes

**Q: Is the switch a permanent live as when my key is out of the ignition the lights still work?**
A: I don't know the answer, but suggest that there must be some current getting past/through the switch, it takes very little to power LED lights. I had an 240V AC 100 W LED floodlight which flickered on every 15 seconds and the current was going through the neon in the switch and charging up the LED's to cause the problem.
