NO UNIVERSAL FLASHER RELAY, often reffered to as camping/trailer relay.
As it is ELECTRONIC(make sure it is) it keeps the same flash rate irrespective of load, ie whether you have two extra lights(trailer) or not on the car.
Bosch/Hella do them, you can get them from loads of places, look in yellow pages under car electrics, the sort you need is ELECTRONIC the sort YOU HAVE at the moment is ELECTRO MECHANICAL.
