# Hazard Warning Switch for Jaguar E-Type Series 1

Vehicle Overview

The Jaguar E-Type Series 1 requires specific attention when sourcing a hazard warning switch, as fitment and originality depend heavily on the production date and engine variant.

Important: Factory Equipment Considerations

Note: Many early Series 1 E-Types, particularly 3.8 litre models produced before 1966, did not come from the factory with a hazard warning switch. Hazard flasher legislation in the US did not take effect until around 1966. If your car is an early Series 1, the hazard switch may be a later addition or dealer-fitted accessory rather than original equipment.

4.2 litre Series 1 models from 1966 onward should have a proper factory hazard switch as original equipment.

Check your dash before assuming a "correct" factory part exists for your specific car.

Fitment Notes

  • Early Series 1 cars featured toggle switches rather than rocker switches (which appeared on later models)
  • 3.8 litre vs. 4.2 litre variants have different dash layouts
  • Switch faces and toggle styles changed several times through the Series 1 production run
  • Early and late Series 1 cars have different switch faces

To identify the correct switch for your car, have your chassis number ready — this will allow you to confirm the exact switch style, toggle type, and whether your specific production date should have factory hazard equipment at all.
