This is an aftermarket flasher for constant 90 FPM blinking speed. It is used for LED bulb installs or for when towing trailers on some vehicles. It has two teminals on the bottom plus a wire lead for a ground connection. This one is from TMI and was bought on ebay for $12. This flasher will not change speed if a bulb goes out. It will NOT work on the 2G Eclipses without some major mods to the factory flasher/hazard unit.
