## 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.
