Perfectly fine

Works just fine, alleviates the need for 3-4 Y adapters for the various lights. would be nice if it came with a little plug for unused ports, or even a 3-end splitter and not 4.

Steve Davis

The splitter is for future add ons but hopefully soon it will be needed

Rear End Lighting Wiring Y Splitters

Love them, absolutely a must have , if you add additional rear end lighting....CIRO is the only lighting TO BUY......AWESOME PRODUCTS !!!!!!!

Charles Dunn
Four way splitter

This splitter allowed me to clean up the wiring mess under my seat.....long enough and allows me to connect up to 4 rear lighting add-ons.....Great product, highly recommend, thanks Ciro

Saves room

These are great to have if you have multiple sets of rear lighting. You only have to make room for one splitter and these are much easier to tuck away under the seat.
