Motorcycle Underglow Laws UK: A Comprehensive Guide

Underglow is becoming a more frequent modification for both car and motorcycle enthusiasts as the lighting system regains popularity. However, before installation, we recommend that every rider should have knowledge of the laws surrounding their use.

Understanding Motorcycle Underglow Laws

It is completely legal to install underglow on your motorcycle, but riders must adhere to UK legislation concerning placement and the colour of lights on display. The laws have been implemented to promote road safety and prevent distractions and hazards for both drivers and riders alike. Non-compliance can lead to fines and even worse penalties. The aim is for all riders to prioritize safe and exercise caution when adding any type of motorcycle modification.


Permissible Colours

On public roads in the UK, only white or amber lights are permitted on your motorcycle, along with the red for brake lights. Riders may utilize the various colours in their kit during car meets, shows or in off-road settings, but as a rule of thumb, you want to avoid using colours that can be mistaken for emergency vehicles by public roads.


Placement Restrictions

Now we know the colours we are permitted to use on public roads while riding motorcycles, it is important to know that under UK law, underglow should not be seen from the front or rear of the bike, to make sure they are not interfering with your motorcycle's front or rear lights and therefore distracting other road users.

Secure installation is crucial to make sure your light bars don't detach while you're riding, causing a major hazard to yourself and others.
