Beck/Arnley Back Up Light Switch P/N:201-1684
Restore the reverse lamps on your Mazda with the Beck/Arnley Back Up Light Switch 201-1641 — a direct-fit replacement sourced to match OE form, fit, and function for the 1979-1984 and 1986-1987 Mazda B2000, the 1982-1984 and 1987-1993 Mazda B2200, the 1990 Mazda Miata, and the 1979-1985 Mazda RX-7.
Mounted on the transmission, this switch senses when the gearbox is shifted into reverse and completes the circuit that powers the back-up lights. If a failed switch is the reason your reverse lights stay dark — or stay on constantly — replacing it with this unit restores that function.
Engine applications vary — see the Buyer's Guide tab for the full vehicle list.
