★ This brake light switch mounts on the outlet bolt at the front of the master cylinder and replaces defective original switches.
Application
The brake light switch is used on vehicles in the categories in which this product is placed: MB/GPW (1941-1945), CJ-2A, CJ-3A, CJ-3B and M38. Fits all models with the early-style frame-mounted master cylinder with threaded front outlet.
Installation notes
The switch screws into the front outlet of the master cylinder, through the brass Y-fitting. The outlet bolt has a thread at the front specifically for the brake light switch. Use the original female bullet terminal connector from the wiring for connection.
Compatibility
This switch is the solid pin/bullet terminal version. For later models with nail head terminals, a different type is required. Note: when converting to dual reservoir master cylinder, an inline switch must be used, this switch does not fit there.
Historical context
The brake light switch on the master cylinder was standard from early WWII production and remained in use until the 1960s. A common problem when brake lights fail is a defective switch, which can be replaced relatively easily.
