This simple upgrade is many times brighter than stock and is totally reversible! Includes a reliable solid-state flasher (with mounting bracket and connectors), two single-function LED bulbs and two dual-function LED bulbs. Start with a good clean ground and connections, then remove the lenses and replace the bulbs - it works great!

For negative ground systems only

To wire up the LED flasher unit, the lighter color green wires goes to center terminal (for the indicator). For the remaining two terminals,  one is power, the other is switched, connect those to the side terminals. If it doesn’t work, switch the two side terminals.
