TO ALL DB MkIII OWNERS
When re-making the switches for the DB MkIII we realised that the electrical loads for the headlamps feed direct through the Hella Dipswitch, this is wrong as it is a potential risk for the (very rare) switch to fail, with the added problem of burnt out loom if it shorts.
The headlamps should be fed via a fused relay, easliy fitted under the dash, the Hella Dipswitch can then be wired as a switch for the relay with minimal loads only.
