What's wrong?
The left-hand combination switch on the 2018 Triumph Street Triple S sits on the handlebar where the rider operates the turn signals and headlight controls. Triumph also calls this part the left-hand switch cube. In normal use, it sends the rider's input through small electrical circuits so the lights respond when the switch is moved. Those lights help other drivers see the motorcycle's direction and position.
On affected motorcycles, water can enter the switch cube and reach electrical circuits that were not sealed well enough. Moisture inside the switch creates unintended electrical tracking, meaning current follows a path it should not take across the circuit board. When that happens, the turn signal switch or the headlight switch can stop working correctly.
Triumph reported no warning sign before failure. The switch can work normally on one ride and then fail after water intrusion reaches the circuit, so a rider will not get a separate early symptom before the lighting control problem appears.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorcycle is included.
What's the safety risk?
Faulty turn signal and headlight switches reduce the rider's ability to signal turns or maintain proper lighting, increasing crash risk. There is no warning sign before failure, so schedule the recall work and use extra care until the switch is replaced. Repair will be free at any franchised Triumph dealer once available.
What should I do?
- Check your VIN to confirm your 2018 Triumph Street Triple S is included in this recall.
- Wait for Triumph's repair notice before scheduling the free dealer repair.
- Contact a franchised Triumph dealer once the repair opens, and ask for the left-hand combination switch replacement that fixes water-related turn-signal and headlight switch malfunction.
- Reference recall number 18V302 when you call Triumph or the dealer.
- Ride with extra caution until the switch is repaired, since turn signal or headlight switch failure increases crash risk.
What happens at the repair
At the dealer, once the remedy is available, a Triumph technician will replace the left hand combination switch on the handlebar. That switch controls the turn signal and headlight functions, so the repair replaces the part that water can damage. The final dealer repair will be free once available, with parts and labor covered under the recall. Repair costs already paid are handled through Triumph's limited warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
