If you’re referring to the lower flog lights on the Foton, access can be gained from behind the bumper. Follow the wiring to where it disappears inside the light mount and remove the globes from there.

For the actual headlights, the globes can be replaced, but it’s a bit fiddlier. You need to remove the plastic twist-lock covers at the back of each headlight to gain access to the globes, but to do that you need to remove the battery on one side and the air-box on the other.

Don’t forget, when changing globes, not to touch the glass part with your fingers. This can leave an oily residue (from your skin) on the glass which forms a hot-spot and can lead to the globe failing prematurely.

The indicator lights on the dashboard are blinking fast because there’s not the usual load on the indicator circuit from the exterior globes. This is a great way to know if you have a blown indicator globe, as the light on the dashboard will flash faster on the side of the failed globe.

So you need to look downstream to figure out why none of the indicator lights are getting power to them. This could be a broken wire, a body-computer problem, a poor earth or some other electrical gremlin that is robbing the lights of their power source and signal. An auto electrician would be a good place to tackle the problem.

The most obvious warning light that features a thermometer icon along with what could be described as fumes is the low coolant warning light which is sometimes yellow or orange (as opposed to red). If that's the case, the `fumes' are actually representing the coolant (as little waves). The other warning light that commonly displays gas fumes is the light to tell you there's a problem with the vehicle's diesel particulate filter (DPF). This is also often a yellow or orange light.

Car-makers tend to save red warning lights for the more serious problems such as low oil pressure or high coolant temperature. Even so, a yellow or orange warning light should not be ignored as it can easily develop into a red-light situation pretty quickly.

It sounds simple, but have you checked the owner's manual for the vehicle? There's likely to be a chapter dealing with what warning lights represent what.
