Ultimate decoder module for H4 headlights / Pair
Product updated on 2019-12-21, SBx Parts -  SBX:LED:ULTH4,  Ultimate decoder module for H4 headlights / Pair, Solves DRL, Canbus and EMF issues. If your vehicle's daytime running lights operate at a voltage lower than 8V, then some LED kits won't even light up. Or if they do the low voltage will reduce their life expectancy. We have the perfect solutions for this problem - our new Ultimate Decoder Modules. They allow you to use any LED kit incapable of running at low voltage DRL, giving it full power, so it always comes on. These modules also provide full Canbus compatibility to all non-Canbus LED kits. The wiring to the battery is only required when using with low voltage DRL and bulbs requiring 12 volts. Plug and Play for Canbus usage., If your vehicle has low voltage daytime running lights and headlights which require a full 12 volts then connect one power cable on each module to the vehicle's light power connector. Connect the other power cable on each module to the new LED bulb from a kit. Connect the supplied power wire to the battery's + and - and then each of the two ends to one of the DRL modules. When the car's headlights are ON (ie. supply is 12V+) then the module does not draw any power from the battery. However, as soon as power to the lights drops below 12V, the module starts to supply the LED lights with full battery power. So, if your DRLs operate at a low voltage (normally 6V), then the modules will always supply power to the lights and they'll work regardless of the minimum voltage required for the led bulbs to light up. Once you turn the car's headlights to ON, the modules will stop drawing power from the battery because it is no longer needed. Package Includes: 2 DRL canbus modules 1 Power cable Specifications: Minimum Required Voltage for modules to work: 4.1V Battery power is supplied when DRL power drops below 12V Module size: 2.5" (W) x 2.5" (L) x 1" (H) Rated Power: 55W (+/- 10%) Actual Power: 50.5W (4.2A@12V) with LED kit connected CANBUS Compatible: YES EMC built-in: YES Cable length: 67 inches (module to module) Cable length: 30 inches (battery to a T-connector where it connects to the module to module cable) Red battery + cable has a built-in replaceable 25A fuse Everything is plug-n-play for easy installation
