How to solve the problem that the oil-gas conversion switch does not light up?

Open the driver's door of the car. Step on the brake pedal to prepare to start the engine; press the one-button start key of the car. All the dashboard lights come on, and the engine starts. Press the top of the toggle lever located on the right side of the steering wheel, hold it down for more than 5 seconds without releasing, and the matching will be completed.

When the fuel switch indicator light is off, I usually start by checking the simpler possibilities first. It could be a burnt-out bulb, which is quite common, especially after prolonged use of the switch. You can try replacing it with a new bulb yourself—it's not too difficult. Another possibility is a blown fuse; locate the fuse corresponding to the gas system in the fuse box and check if it's blackened. If replacing it doesn't help, it might be a wiring issue, like a loose plug or a short circuit. I'd gently wiggle the plug to see if there's any response. Sometimes, the switch itself is faulty, or there's an unstable system voltage. For safety, don't force it—it's better to take it to a repair shop and let them diagnose it with professional tools. It's a good habit to regularly check this area to avoid sudden issues while driving at night.

I've driven several modified LPG vehicles and encountered situations where the switch lights wouldn't turn on. Checking the fuse first is the quickest solution - it's usually located in the fuse box near the driver's seat, marked LPG. I always carry spare fuses for immediate replacement. If the fuse is fine, it might be a burnt-out bulb, which isn't too troublesome to replace. However, wiring issues can be more problematic, like loose connections from the modification. I've tried tightening them myself, but when that doesn't work, I have to consult a professional technician. I remember one time when I delayed repairs too long and the switch failed completely, making it impossible to switch modes while driving - quite dangerous. That's why I now regularly use a multimeter to check voltage as a preventive measure.

Lights not turning on? Don't panic. As someone who enjoys DIY car repairs, I'd first check the fuse. Open the fuse box, locate the fuse related to the lights, and try replacing it with a new one. Alternatively, the bulb might be burnt out - just remove the switch cover and replace the small bulb. These are all DIY-level fixes that are simple and cost-effective. However, if there's a short circuit or poor connector issues in the wiring, that's beyond DIY scope - I'd recommend visiting a repair shop directly. Safe driving is crucial, never ignore lighting issues in dark conditions.
