The turn signal of the Surui is not working due to a bulb failure. Reasons for the light not working: The lifespan of a bulb is limited, and when it ends, the bulb naturally stops working. If the bulb's fuse is blown, the bulb acts as an open circuit and will not light up. Additionally, if the contacts in the lighting relay or combination switch become corroded or stuck, the circuit may fail to open or close properly. Solutions for the light not working: Set the light switch to the headlight position and use a test light to check the "hot wire" terminal of the dimmer switch. If the test light does not illuminate, check the corresponding terminal of the light switch with the test light. If the test light illuminates, it indicates a broken wire between the two switches. If the test light does not illuminate, the light switch is likely faulty. When checking the terminals of the dimmer switch, if the test light illuminates, the dimmer switch is defective.

I also encountered the issue of the turn signal not working on my Surui. At first, I was quite anxious because others couldn't see my intentions when turning. I first checked the bulb, as a burnt-out bulb is the most common cause. Bulbs are cheap and easy to replace—just unscrew the lamp cover and put in a new one. If it still doesn't work, check the fuse next. Locate the corresponding turn signal fuse in the fuse box under the hood and see if it's blown. Replacing a new one costs just a few dollars. If that doesn't fix it, it might be a short circuit or a faulty relay, in which case you should take it to a professional repair shop, as tampering with the wiring yourself can lead to more problems. When driving, I regularly open the engine compartment to check the bulb status, which can save a lot of trouble. Safety comes first—fix a non-working turn signal promptly to reduce the risk of accidents.

As an ordinary person, don't panic if you find the turn signal isn't working - start with simple steps. On my Surui, I opened the hood to check if the bulb socket was loose. Bulbs tend to fail easily when aged, and replacing them usually solves the problem. Then locate the fuse box, typically on the driver's side - replace with a spare if the fuse is blown. If that doesn't work, it might be poor switch contact or wiring issues, like rainwater causing a short circuit. In such cases, it's best to test voltage with a multimeter, or head straight to a repair shop if you're unsure. Remember not to delay repairs - malfunctioning turn signals are dangerous on the road, affecting turning anticipation. Have technicians check them during regular maintenance for preventive care and peace of mind.

A non-functioning turn signal directly impacts driving safety, as other drivers cannot see your intended movements, increasing the risk of rear-end collisions or turning accidents. Common causes on the Surui include bulb failure, blown fuses, or aging wiring. It is recommended to stop immediately and inspect the bulb and fuse. If the issue is confirmed to be simple, replacing the parts yourself can save time. For more complex situations, such as a faulty control module, seek professional repair promptly to prevent further damage. Developing a habit of checking bulbs monthly during regular driving can help prevent such issues.
