Straight answers on fitting and wiring the Yoshimura Micro Turn Signal Kit to the rear of your 2021-26 Honda CRF300L or Rally, including running-light behavior and common install snags.
Quick answer
For a 2021-26 CRF300L or CRF300L Rally, the Yoshimura Micro Turn Signal Kit is a direct, complete solution for the rear: it includes the micro lights and the parts needed to mount them. Plan on basic wiring connections and confirming your local rules for rear running lights.
Why the rear is the fussier end
The rear of the CRF300L carries the plate holder, rear fender and stock signal stalks in one crowded area, so clearance and wire routing matter more than they do at the front. The kit is designed for this position, but you still need to check that the new signals clear the exhaust and any luggage or tail tidy you have added.
The Rally shares the same rear signal layout for this application, so the same kit and the same install sequence apply. Differences between the two models are mainly bodywork and dash, not the rear turn signal mounting points.
Running light behavior and legal checks
When used at the rear, the Micro Signals also function as running lights. That is useful for visibility, but running turn signals are not permitted in every region. Check your local inspection or road rules before you rely on that function, and decide whether you will wire the running-light circuit or leave it disconnected.
CRF300L rear micro signal FAQ
- Will this kit fit my 2021-26 CRF300L or Rally?
- Yes. The kit is made for the 2021-26 CRF300L and CRF300L Rally and can be used at the front or rear. If your bike falls outside that range, do not assume fitment. Confirm your model year before ordering.
- Do I need extra parts for the rear install?
- No. The kit is custom made and comes with everything you need to install the Micro Lights at the rear. Reuse your existing mounting points and hardware unless the kit instructions say otherwise.
- How do I wire the micro turn signals?
- Connect the kit's signal leads to your bike's rear turn signal circuit, matching left and right. If you want the running-light function, also connect the running-light lead to a switched power source. Use the supplied connectors and test each side before you button up the bodywork. Test left and right separately before final assembly.
- Will the rear signals work as running lights?
- Yes, when used at the rear these signals also work as running lights. That is a visibility benefit, but check whether local rules allow running turn signals before you enable that circuit. Verify local lighting rules first.
- Are the micro signals bright enough for road use?
- Yoshimura states the Micro Signals are among the brightest on the market despite being roughly dime-sized. Brightness alone does not guarantee legal compliance, so confirm local requirements for turn signal size and placement.
- Can I use this kit with a fender eliminator or tail tidy?
- The kit is designed for the stock rear signal location. If you have changed the tail, check clearance and mounting depth before installing; the kit does not include adapters for aftermarket tails. Aftermarket tails may need separate brackets.
