Abstract: A road vehicle road vehicle direction indicator light system 1 comprises front and rear lamps 2, 4 for the nearside and front and rear lamps 6, 8 for the offside of the vehicle, a battery 10 power source connected to an ignition switch 12, a hazard warning switch 14 and a flasher control unit 16 connected to an indicator switch 18. With the exception of the flasher control unit 16 the other individual elements of the road vehicle indicator light system 1 are fairly standard. The flasher control unit 16 is electronically controlled and comprises a microprocessor having a plurality of selectable lamp flash sequences stored in a non-volatile memory. The lamp flash sequences maybe pre-programmed into the non-volatile memory. Each flash sequence is assigned a unique number within the microprocessor coding. The flasher unit 16 has a receivable input signal from the indicator switch 18. The flasher unit 16 controls the frequency of the on/off flashing of the lamps 2, 4, 6, 8.
