Hello,
We are sorry to hear that your lights are not working correctly. The instructions indicate that the wiring is very straightforward and they have integrated LEDs pre-wired inside the unit and there is no switch to select only one of the lights to be on. This is a very unusual issue, and even more so given that all 3 are doing the same. However, they do appear to be faulty and unfortunately we can only offer replacements or refund, if they are still under guarantee.
Thank you for using Screwfix Q&A.
