New item, open box. set of 2 【EFFECTIVE AND STABLE ELECTRICAL PROPERTIES】Operating voltage range between 11V~30V. Pair 32pcs 5 watts high lumens led chips can output 18800LM. Use premium high temperature resistance electronics elements to form high usage circuit, include IC, capacitance and inductance etc. reduce heat generation to make the driving light’s lifespan more than 50,000 hours. Meet EMC anti-interference standard. The spot lights can work normally between -40 degree Celsius ~ 100 degree Celsius. 【EFFICIENT LIGHTING EFFECT】Each Led off road light cup is combined with spot and flood beam design. Spot beam travels quite far out and has a nice width. The amber offroad light emits super bright amber light. Give safe view in most of bad weathers like rainy days, foggy days and snowy days, make driving safer. 【PREMIUM COMBINATION OF MATERIALS】High thermal conductivity PCB board, high strength ADC12 aluminum housing, spotlights can conduct heat quickly. Housing surface is deal with salt fog-proof, 316 stainless steel screws. It's anti-rust and more durable.
