Undercar Neons: Are they legal?

Unfortunately, this is not a simple question to answer. In theory, they are legal providing that you follow these rules.

You MUST NOT be able to see the actual tubes. As long as all you can see is the GLOW then in theory they are not causing a problem. Of couse we recommend that if you have them fitted you have a switch to turn them on and off.

They must not cause a distraction to yourself or other road users. To be honest if they're turned on it could be said that you're distracting other drivers, it all depends on who is dealing with the matter.

If you are stopped by the police, be courteous and polite. If you are asked to switch off the neons we suggest that you do so or they could issue you with an order to remove them.
