Defender TD5 / TDCI Aux Light Switch for front Fogs or for other lighting you have. Many people like to add lights o their vehicle and use and original looking switch to keep the dash looking the same. On the Defender TD5 and the TDCI earlier models did not have these switches and were an optional extra. Now you can replace the blanking switch with one of these new switches. Light on the switch illuminates to show its in use.
