What is the reason why the Lavida's high beam does not light up but can flash?

[LeGabrielle]

Lavida's high beam does not light up but can flash for the following reasons: High beam circuit failure: It could be an issue with the high beam bulb or the high beam circuit. It is recommended to have a detailed inspection at a 4S shop. If the high beam does not light up, it is advised not to drive at night. If the indicator light does not illuminate, it may be due to a faulty bulb or a problem with the bulb circuit. Fuse blown: It could be that the power cord plug is not securely connected. It might also be due to a blown fuse. Poor light wire connection: It could be due to poor contact in the light wire interface clip. It is recommended to replace the contact clip. If the high beam does not light up, check if the high beam is installed incorrectly.

My Lavida had the same issue before—the high beams wouldn't stay on continuously but would work intermittently when flashing. After some troubleshooting, I realized the high beam switch contacts were severely worn, causing poor contact and preventing current flow when kept on. The flashing function, however, used a separate circuit and still worked fine via the flash switch. Later, I disassembled the combo switch myself and found the contacts covered in rust. A simple cleaning fixed the problem. If you frequently drive at night, high beam issues are especially dangerous—don’t delay checking the contacts or replacing the switch. Safety comes first. I’ve met other owners who ignored it, only to end up with a completely failed lighting unit, costing more in repairs. During routine maintenance, periodically inspect the contacts and keep them dry to extend headlight life. This is a common minor flaw in Lavida models, but addressing it ensures safer driving.

I'm a car enthusiast who often researches minor issues myself. One possible reason why the high beam on the Lavida doesn't stay on but can flash is that the bulb filament is partially broken. When set to constant on, the broken end can't make contact, but the high current surge during flashing can momentarily reconnect it and make it light up. Another common cause is aging of the high beam relay or switch, where the contacts in the constant-on position are worn out. You can do a preliminary test: if the high beam doesn't respond when set to constant on but lights up when you push the flash lever, it means the flash circuit is working. Check if the bulb is half-broken or measure the contact resistance of the switch—high resistance indicates a contact issue. I've personally tried cleaning the contacts or simply replacing the parts, which isn't costly. Remember to disconnect the battery to avoid short circuits while working on it. Once fixed, the high beam will work normally, making night driving much easier. Such issues are quite common in this model, and trying to fix it yourself can save a lot of money and time.

While driving, I noticed that the high beam continuous mode is not working, only the flash function is operational, which worries me about driving safety. It's possible that the continuous mode of the combination switch is faulty, with worn contacts causing an open circuit. The flash function operates independently and can serve as a temporary emergency measure. Don't underestimate this issue; driving on highways at night without high beams is very dangerous, so it must be repaired promptly. The inspection method is simple: check if the fuse is intact, then test the switch contacts. It's best to visit a professional shop to replace the component; the cost is not high but can be life-saving. Safety comes first.

My Lavida has this issue during long-distance drives—the high beams won't turn on, but the flash function works. I was really nervous, afraid something might happen after dark. I consulted my auto repair friends, and they said it's often due to oxidation of the constant-on contacts in the combination switch, leading to poor contact while the flash circuit remains intact. I didn't tamper with it and went straight to the 4S shop to replace the switch module, which cost a few hundred yuan to fix. In daily use, the headlight switch is frequently operated, and over time, the contacts are prone to rust and wear. I recommend car owners not to ignore this and address it early. After the repair, the high beams shine brightly, making driving much safer.

In automotive circuit design, the constant illumination and flashing of high beams are controlled by different modules. On the Lavida, when the constant illumination function fails but the flashing still works, it usually indicates severe wear on the constant illumination relay or switch contacts, leading to a lack of current conduction. The flashing switch operates independently, so it remains unaffected. Contact issues often arise from daily switch wear or oxidation. Understanding this, I tested the voltage difference to pinpoint the problem. The solution can involve cleaning the contacts or replacing the components. Such faults are common in Lavida models, and repairing them restores normal high beam functionality.
