A headlight with a built-in horn, a taillight with turn signals and a brake light, and a single handlebar switch to run them, made for UART-version Bafang BBSHD, BBS02 and BBS01 kits. It turns a trail conversion into a bike you can ride home in traffic after dark.
Most BBSHD kits ship with a small headlight at best, switched from the display and with nothing at the back. Powallon's kit fills the whole gap. A headlight with a horn built in goes on the front, a taillight with turn signals and a brake light goes on the back, and one switch on the bar runs the lot.
Each piece does a specific job:
The signals sit in the taillight only, so drivers behind you see your turn and drivers ahead do not. That is still the side that matters most on a fast road bike, where cars come up from behind at speeds far closer to yours than on a pedal bike.
The kit is built around Bafang's own wiring, which is why the brake light can react to the kit's brake sensors without a separate switch on the lever. That same design choice sets the two rules that decide whether it will work on your bike: the protocol and the brake sensors.
For the rest of the handlebar layout, from display to throttle, the display guide maps what sits where.

Powallon designed this kit for the UART version of Bafang's mid drives only, and asks buyers to check the plug on the motor's wiring harness before ordering. UART and CAN-bus kits use different connectors and a different language between parts. A CAN-bus BBSHD will not run this kit.
Check these before the box arrives:
If your controller turns out to have no light output, a newer controller with the port solves it. The BAFANG replacement controller is the version with gear-sensor and light ports. With protocol, port and voltage confirmed, the rest of the install is routing cables.
A BBSHD bike cruises at speeds that put it in the traffic flow on urban roads, not beside it. That changes what lighting has to do. Being seen from behind, showing when you slow down and signalling a turn without taking a hand off the bars all matter far more than on a pedal bike.
The kit's features line up with the moments that go wrong in traffic:
Cargo riders get the most out of the switch. With a child seat or a full load of groceries, taking a hand off to signal is the last thing you want on a busy road. A thumb press on the switch keeps both hands on a bike that weighs far more than it looks.
Powallon rates the kit as water resistant rather than giving an IP number. Rain is fine; pressure washing the lamps and the switch is not. Seal every connector you make with dielectric grease and route the rear cable where a pannier or kickstand cannot pinch it.
On long bikes, the run from bar to taillight gets long. Plan the route along the frame before cutting any zip ties tight. Harness routing on longtails and trikes is handled in the install guide.
Powallon adds a warning that saves a lot of confusion: always use the original brakes and sensors that came with the kit. Line-through brake sensors, and sensors with indicator lights, can leave the taillight glowing constantly. The brake light reads the same signal the controller uses for motor cut-off, and some aftermarket sensors hold that line in a state the taillight reads as braking.
If the taillight stays lit with the levers released, work through it in order:
Fitting the kit itself follows the usual order. Mount the headlight on the bar or fork crown, the taillight on the rack or seatstay, and the switch within thumb reach on the left grip if the right side is crowded. Route cables, make the connections at the harness, then test every function with the bike on a stand before riding.
Against the basic headlight many kits include, Powallon's kit is a full system rather than a single lamp. Choose it if you ride on roads after dark and your controller is a UART unit with a suitable light output. Skip it for a CAN-bus kit or a trail-only bike that never sees traffic.
No. Powallon designed it for the UART version of the BBSHD, BBS02 and BBS01 only. Check the harness plug on your motor before ordering.
Many BBSHD controllers supply around 6V on the light lead, but it varies by controller version, and some have no light port. Confirm your controller's value before connecting lamps.
The brake light reads the brake sensor signal. Line-through or indicator-LED brake sensors can hold it on, so use the original Bafang kit sensors.
No. The turn signals are in the taillight. The headlight carries the light and the horn.
