Important info about headlights & relays

Advantages & Features:

  • Brighter headlight. Stock & after-market bulbs are brighter because the full battery voltage reaches the bulb.* Allows use of higher wattage bulbs without fear of overload - a fried wiring harness is expensive to replace. A must have to use with additional headlights. There are solid-state "relays" for both the high and low beams.
  • Protects switchgear. Your bike's existing light switch will now only carry milliamps to control the solid-state "relay" kit doing the heavy lifting carrying many amps. Your switchgear may last forever.
  • EZ install & very small. Plug-in kit with no wire cutting. Quick disconnect wire terminals on module for battery supply enabling easier install. Amazingly small solid-state "relay" module. See quarter.
  • All solid-state. Heavy duty solid-state module components give higher reliability and durability than older mechanical relays. Solid-state uses less power and does not cause arcing which degrades parts. Faster switching.
  • High amps. Heavy duty 15 or 15 amps rating. That's a lot of power! Requires 12 volts DC.
  • Single or dual headlights. A kit is available for H1, H3, H4, or H7 single or dual headlights. The solid-state relay is a must have when using additional headlights to avoid frying the factory wiring harness.
  • Horn or siren. Universal kit will be available for auxiliary accessories. 
  • Existing headlight modulator. Just connect your existing headlight modulator's input into the kit's output.
  • All-in-one. Different kit available with a headlight modulator and solid-state "relay" functions in one module. All-in-one description here.
  • Twelve month limited warranty.

    Note: the solid-state "relay" kit outputs will be OFF if the high and low beam kit inputs are ON (+12 VDC) at the same time.

    * This can be as much as 1.5 volts difference between factory wiring and solid-state "relay" kit. The brightness is significantly noticeable on 12 volt halogen bulbs.
SPECS: Heavy duty solid-state "relay" parts (no mechanical relays); 15 or 20 amps capacity; on resistance is almost zero ohms; high heat resistant H4 female and/or male connectors; fuse holder; ring battery terminal connectors; waterproof module.
