Features: Using COB chips, the ultra-thin plate shape design makes the installation fit better, the illumination is more uniform, and avoids the disadvantages of poor illumination width caused by point light sources. Suitable for 10-13V voltage, COB products have light source diffusion, wide-angle irradiation, high lumens, low power consumption, long life, and can save electricity and fuel. No delay in lighting, high light purity, strong color rendering and penetrating power, suitable for all systems using 12v power supply, and widely used. Using LED light-emitting diodes, low power consumption, better protection of car circuits, replacement of combined instrument panel, A/C lights, dashboard instruments, climate control bulbs. LED has no filament, good heat diipation, low current, low calorific value, not easy to oxidize the vehicle circuit, strong shock resistance, low temperature rise, is a revolutionary solid-state light source. Specification: Material: engineering plastic Size: 0.39*0.20*0.31in/1.0*0.5*0.8cm Color: white, blue, red, green, yellow Voltage: 12V Uses: instrument lights, warning lights, etc. Package Includes: 10pcs
