The Optronics HLL88/89 Series DOT-compliant high and low beam sealed LED headlamps are designed to replace standard 4” by 6” sealed beam halogen and HID headlamps. Their light output is whiter than their incandescent counterparts for greater visibility. They are also designed to last long and be energy efficient, and they are well-suited for use with 12VDC or 24VDC systems. They have also received an IP69K rating.
