Triumph TR5-250 Headlamp Control Relay Kit - 6 Cylinder
The TR5 and TR250 electrical system does not include relays in the headlamp dip or main beam circuits. The omission of relays from these circuits means that the high electrical currents required to power the lamps runs through the switchgear when the lamps are used. This is contributory to the burning and subsequent failure of light switch and dip switch contact points. This situation is aggravated if the original equipment headlamps are uprated to a higher wattage or supplemented with additional lights, as this increases the current load on the existing circuit. Another benefit to the installation of operating relays is that of brighter headlamps without uprating their wattage. All TRs easily lent themselves to the installation of relays to control headlamp operating power without having to do any butchery to the wiring loom that is non reversible. It also pays back by not involuntarily melting the dip, flash or main lighting switch. The additional wiring and relays can be easily tucked out of sight so as not to inflame the wrath of the purists.
