Billet Proof's handlebar-mounted front brake light switch replaces HD# 71590-96 and provides a plug-and-play replacement with 50" of wire for many Harley models from 1996–2017. This compact switch is designed to meet or exceed OEM standards while giving you enough wiring length to route cleanly along your handlebars and frame. It ships individually and fits a wide range of Harley-Davidson motorcycles including Touring, Softail, Dyna, Sportster and V-Rod families. The extra 50" of wire simplifies installation and reduces the need for extensions or splicing when you mount it in non-stock positions.

Which Harley models will this switch fit?

The Billet Proof switch covers many popular Harley platforms across multiple years, making it a versatile replacement part for riders with older and newer bikes. It’s engineered to be compatible with both US and international model wiring harnesses for the stated years.

  • 1996–2013 Harley Touring FLH/FLT models
  • 1996–2013 Softail FXST/FLST models
  • 1996–2013 Dyna FXD and Sportster XL models
  • 2002–2017 V-Rod (VRSC) models

How does the 50" wire make installation easier?

The generous wire length gives you flexibility to route the cable neatly without needing additional extensions. That reduces connectors and potential failure points while making it easier to tuck wiring into fairings or along the frame for a factory look.

  • Allows routing along handlebars, through risers, or under trimmings
  • Minimizes need for splicing or extra connectors
  • Helps achieve a clean installation with less strain on terminals

Is this switch a reliable aftermarket replacement?

This Billet Proof unit is manufactured to meet or exceed original equipment specifications for fit and function. It’s sold individually and intended as a direct replacement for Harley part number 71590-96, providing the same switch action and electrical connection as the OEM item.

  • Built to match OEM fit and operating characteristics
  • Replaces HD# 71590-96 for direct swap compatibility
  • SOLD INDIVIDUALLY—order quantity accordingly for both sides if needed

What should you know before you buy?

Check your bike’s model and year against the compatibility list to ensure correct fit. Although the wire length offers installation flexibility, confirm routing paths and mounting location on your handlebars to avoid excess tension or interference with controls.

  • Verify compatibility with your specific Harley model and year
  • Plan routing to prevent rubbing against moving parts
  • Confirm you need a single switch; purchase additional units separately
Who is this for: This front brake light switch is aimed at DIY mechanics, restoration builders, and riders replacing a worn or damaged OEM switch. It’s especially useful when you want a straightforward, OEM-compatible replacement that simplifies installation thanks to the extended 50" wiring. Whether you’re returning a touring bike to roadworthy condition or upgrading controls on a custom build, this Billet Proof switch provides a dependable, direct-fit option without altering the bike’s original electrical behavior.
