1.  It will increase the voltage to the headlight bulbs by over 2 full volts!  In a standard 12 volt system, that is  a 20% increase to the bulbs.  More power = brighter lighting.

2.  For those riders with using a larger wattage bulb, it will safely handle the extra load the factory electrical system was not designed to. 

We utilize larger diameter wire to reduce resistance, relays that are designed to handle much more power than the factory units, with a primarily plug-&-play install. 

The relays are in a plug-in base so that should replacement be necessary, it is as simple as possible.  The main power lead is fused for additional protection.  We use 90 degree connectors for plugging in to the bulbs as most OEM motorcycles do.

Two models available; H4 single and H4 dual for 2 bulb headlight housings.

Fitment: universal for H4 headlight
