According to the state’s laws, vehicle lighting equipment that is non-mandatory or extra must be certified by the manufacturer as legal.

  • Light type: If any motor vehicle wants to attach aftermarket lighting, it should be certified and in compliance with the state’s regulations. Neon underglow lights do not have this type of certification and are therefore considered illegal.
  • Size: There is no mention of the permitted size of aftermarket lighting within the code.
  • Permitted colors: The permitted colors for any aftermarket lighting that is visible from the front of the vehicle must be amber, yellow, or white. Any visible light on the rear of the vehicle must be amber or red. Civilian vehicles cannot have a visible red light on the front of the vehicle.

Based on current Connecticut laws, underglow neon lights are illegal in the state. The usage of any auxiliary lighting system requires certification to show compliance with the state’s rules and regulations. However, most of the underglow neon light manufacturers don’t certify their products.

Though technically you can install underglow lights for private property use, it is not recommended. Given the state’s rigorous laws regarding the use of public roads with illegal aftermarket lighting even turned off, these lights can get you into legal trouble.

Revolving or flashing lights are permitted for use on motor vehicles. These lights are reserved for emergency vehicles. There are restrictions on the usage of colors too. Certain colors like blue or flashing green lights are only permitted for authorized emergency vehicles.

These state legislative regulations may differ in certain counties and cities of Connecticut. Always verify the laws with your local authorities to avoid getting penalized.

Fines and Penalties for Driving With Underglow

Though the state code deems the usage of aftermarket lights illegal, it does not specify a penalty for a violation of the rule.

Generally, a violation of the lighting law results in a civil infraction. This results in a fine and an opportunity to fix the violation.
