Jet Lites Dual A-51, X-51 – 2012 Mtbr Lights Shootout

Lights Lights Shootout

The new A-51 and X-51 are good lights but what if we can have two of them. Share the mount and the battery and charger to offset the costs. What we end up is a light with twice the light at only 50% higher cost.

Specifications for the A-51 X-51 Dual Light System:

  • Price: $300.00
  • Claimed Lumens: 1700 Lumens
  • Light Head Weight: 188 grams
  • Installed Weight: 484 grams
  • Run Time: 1.5 Hours
  • Measured MTBR Lux: 122 Lux


  • Good battery and charger for the price and upgrade paths are available
  • CNC’d head unit is A+
  • Bar mount and helmet mount are excellent
  • Helmet mount crash detach feature is a good safety feature
  • US made and US supported.
  • An A-51, A-51 combo works real well. But an A-51, X-51 is going to be a world beater


  • Maybe two X-51s can satisfy your lumen appetite too.


We spent hours talking to David on the phone and many months testing his lights.Some of the highlights we’ve noticed are:

  • Lights are designed and manufactured in the USA
  • Casing is CNC’d to the highest standards to be durable and to have the best heat dissipation
  • LEDs and boards are optimized to transfer heat efficiently to the casing and protect the LED
  • Electronics protect the LED from overheating
  • Batteries are tested and the best available are used.
  • Handlebar mount is quick release and can hold two light heads. Adaptors may be available to mount a GoPro or Contour camera in the future.
  • Helmet mount features a breakaway design to protect the rider’s neck in the event of a crash.
  • Charges are well designed and extremely safe. They optimize safety of the user and long life of the battery.

So what’s not to like? It’s US made, well designed by a company that knows their stuff and backs up the product for years to come. Jet Lites, based in Reno Nevada is conservative about making claims about their products and they always try to ensure their customers are taken care of. They’re very active in the local mountain biking scene too as they support local groups, events and festivals.

So is the light any good? That’s where mtbr comes in. We’ve ridden with this light and the predecessor A-51 for many miles. The design is solid as the light is robust and the mount is one of the best.
