Compatible: almost anywhere. Focused directional lighting. Simple installation. All of these attributes culminate for an affordable yet incredible quality piece. Switchback Function: Not only an ultra-bright indicator, but packed with a trick running light in bright white. Wire it up to be part of your overall lighting setup, then when you use your turn signal, it changes to amber. Hit the blinker cancel button and back to white it goes in a trick "fade on" function. Nothing like it on the market until now. A small detail, but a neat one none the less. Dont want to have the white light wired up? Dont wire it in. Easy as that. Custom Lens: covering the switchback LED is a custom clear polycarbonate lens designed to aim the light of the LED in just one direction. This reduces blinding light where you dont want it, but stellar visibility where you do. Waterproof. Wash proof. No matter how much water, mud, or soapy goodness your bike sees, these indicators can handle it. Hard-anodized CNC aluminum bases and hard epoxy coated circuit boards ensures the longest of lives. Can-bus: If youre riding a BMW or other CANBUS-equipped bike, these may need other provisions for proper function if youre replacing your stock turn signals entirely. If youre just adding these in conjunction with the OEM turn signals, they should draw so little power that the bikes computer wont be of the wiser.
