Hazard Warning light – kit installation

Time to fit: 1.5 hours

Hazard warning lights are taken for granted on modern cars but for our little 500’s this was not an option. In these days of increased traffic volumes and speed then some means of visual warning of a breakdown is vital and as our cars are prone to the odd roadside rest then Indicator flashers are a sensible idea.

For those of us who like to keep our cars original then having modern accessories is not always acceptable, but something to increase our safety might be deemed a good idea, especially for those members who do long distance touring.

Another reason not to have a modern extra is appearance and originality, so I hunted around and found a couple of solutions that could be easily fitted and if required hidden from view!

All solutions are essentially the same:

  • Switch with the Hazard logo with internal lamp
  • Relay
  • 4 wires

There are a number of retro fit kits that can be purchased and designs vary, the one I like best is for a motor cycle (circular switch and remote relay) other “Car” ones usually are bigger with switch and relay on a bracket. Whatever you choose installation is similar and very simple and on a 500 the added advantage is that all the wires to connect to are conveniently behind the dash switches and all come with their own instructions.

(Important – read and use those instructions as they may differ from my notes below)


**First job Disconnect the battery terminals**

  1. Locate the switch – Fasten to bulkhead near or behind the windscreen washer plunger. (If using the kit without a bracket then make a “small” L bracket to take the switch)
  2. Feed the wires through to the bonnet via one of the suitable holes nearby. (Don’t forget to fit a rubber grommet into the hole to protect the wires). (If using the kit with remote Relay then fasten this to the bonnet hinge stay unit with a small nut and bolt an ideal location is on the opposite side to the original flasher unit)
  3. Wiring – Connect the Red wire with the fuse, tap onto the Red +ve wire from the ignition switch
  4. Connect the Black or Green Yellow wire to a suitable earth point. (The one where the flasher unit is bolted is ideal)
  5. Connect the 2 Grey or Blue wires onto the cars indicator wires. These are located in the mass of wires coming from the steering column (behind the Speedo in the bonnet) Blue wire is LHS indicator and the Blue/Black wire is RHS indicator. 1 wire to the LHS and 1 wire to the RHS
  6. Finally Reconnect the battery and click the Hazard switch – all 6 indicators should flash!
