one is usually under by the fuse/steering wheel area held in by a clip and one under the radio area also by a clip/ I went leds and had to use a electronic relay// careful some electronic relays are sold as such but are (electro mechanical) electromagnet relay and still need some kind of (load) to trip the circuit //get a (solid state one) it will have a pig tail for a ground !!! I LOVE LEDS nice and bright with polished lenses //the amber bulbs in the front say I AM HERE!!!! and the rear say here's my A__ __ !!! as for as them staying ON bad ground /dirty bulb sockets and the bulbs aren't drawing enough current to heat the metal strip in the relay // the one linked is a (electromagnetic) use this one // this will blink with NO bulbs in there sockets !!!!
