Wired E-Bike Tail Light with Brake Signal, 36V/48V (generic)

Wired tail lights are common original equipment on rack-equipped e-bikes and simple to replace. They mount to the rear rack's standard light tab (or a seat stay bracket), run on the main pack via a 2-pin lead, and the better ones flash brighter when you brake using the brake-sensor signal. Generic units are sold rated for 36V/48V or a wide 12–80V range; check which your bike needs and how many wires the original used (2-wire power only vs 3-wire with brake input). A rack-mount light sits low and is easily blocked by panniers, so keep it visible.

Key considerations

  • Voltage rating must cover your pack
  • 2-wire vs 3-wire (brake signal) — match your harness
  • Rack tab spacing is usually 50 or 80 mm; confirm
  • Keep it visible above panniers or bags

Pros

  • Always powered
  • Brake-light function on 3-wire versions
  • Standard rack mount

Considerations

  • Wiring needed
  • Low mounting position
  • Generic quality

Compatibility notes

  • 36V/48V (or 12–80V rated) systems with a wired tail-light lead; brake function requires a brake-signal wire from the controller or levers

Wired E-Bike LED Headlight, 12–80V Input (generic)

A headlight wired to the main battery never needs charging, and the wide-input versions (commonly rated 12–80V DC) work on 36V, 48V and 52V systems without a converter. Most come with a 2-pin lead for the controller's light output or a direct battery connection, a fork-crown or handlebar bracket, and some include a horn button. The good ones have a proper cutoff beam so you do not blind oncoming traffic; the cheap ones are floodlights. Check the connector on your bike's light lead (often a 2-pin Julet) and whether your display can switch the light.

Rear RacksFeatured

Topeak Explorer Rack (Disc Brake version)

The Explorer is Topeak's everyday aluminum rack with the MTX QuickTrack plate on top, which opens up the whole MTX bag and basket line. The disc version has offset legs to clear rear disc calipers. It bolts to frame eyelets at the dropouts and seat stays and is rated for around 55 lb, which covers panniers and a trunk bag but not a passenger. On e-bikes, the common snag is that the rear axle area is crowded by hub-motor wiring and torque arms, so leave slack in the cable and use the included spacers. It is a reliable, affordable rack for bikes that did not come with one.

Best for: E-bikes without a stock rack · Commuters who want MTX bag compatibility · Disc-brake bikes
