Auxiliary lights provide you with better and stronger illumination of the roadway. Several manufacturers present excellent additional equipment, like AAIWA and ONLINE LED STORE lamps. They have low power and can be used when driving around the city and on off-road vehicles. Such lamps are usually installed using standard mounts with an approximate diameter of 17 mm. They are simply clamped on the steering wheel quite securely. There are almost no other mounting options for auxiliary lights. 4.5-inch ONLINE LED STORE headlamps are installed as the main ones in the Harley Davidson motorcycle headlight housing.
