I will be offering repair services for the FC headlight switch. This is a common issue on all FC models. The main symptom is part of your lighting system wont work. So you can have headlights working but no tail lights  , or none at all. The issue that will cause this is an onboard relay that goes bad, so the unit will need to be opened up in order to replace the relay.
 
*KEEP IN MIND IF YOUR HEADLIGHT HARNESS IS BURNT OR DAMAGED YOU WILL NEED TO FIX OR REPLACE BEFORE INSTALLING REBUILT HEADLIGHT SWITCH. FAILURE TO DO SO WILL CAUSE DAMAGE TO REBUILT SWITCH. 
I also offer repair services for burnt or damaged headlight harnesses as well. That service will consist of replacing the affected wire & replacing the burnt out connector.
Beefing up the harness with an added relay will also be an option that will be available. Check the services tab or look in the RX7 FC page for that service. 
The price covers the work & shipping back to you. 
 
**This is a ship in service.  You will need to ship your switch to the address located at the top of the website.
