LIGHTING SWITCH R.H. (BLUE WIRE)
Right-hand handlebar lighting switch (blue wire lead) from the Lucas control assembly used on early-'70s Triumph handlebar setups.
This is the right-hand handlebar lighting switch, wired with the blue lead, off the electrical setup Lucas supplied for Triumph handlebar control assemblies in the early '70s. It's the switch cluster that sits on the right side of the bars and handles the lighting circuit for the machine. The alias number SPX019 refers to the same physical part under a Sparx-branded reissue number, and the old factory number 54033667 is the earlier version of this same switch that it superseded.

It shows up across several catalog listings for handlebar and control lever assemblies, and also appears in the electrical equipment section of the parts books, which tells you this is wiring-harness-connected hardware, not just a bracket or lever. The catalog spread on this one runs 1971 to 1973.
If you're chasing an old bike's electrics and the switch housing is cracked, sticky, or the contacts inside have gone intermittent, this is the part number to be pulling. Confirm your bars and existing harness connector match up before you order, since handlebar switchgear on these old Brit bikes can vary in mounting and connector style even within a similar year span.
