Default Is it a fuse problem

I have an interesting problem with head lights and tail lights. After a 900 KM trip I see some lights not glowing. This is what I observe

- Upon lock/ unlock using remote: only side lights in RHS head light and LHS tail lights glow
- Turn on lights: Head lights come on, but small lamps in RHS HL set do not come on and only one side of the tail lights glows (forgot which one)

Can any one point out whats wrong, I suspect a blown off fuse.

Check the bulbs. Mostly they are blown. Also check the voltage your alternator is putting out. Any decent battery shop will do that for you

Is it possible that so many bulbs have burnt at the same time? If alternator is putting out less voltage it might be possible, is that what you mean ?

There is a regulator in the alternator which gives out the right voltage, when this goes kaput, there is a surge whenever you revv the engine & that could blow many electrical components starting from the bulbs.

Check bulbs this seems to be a bulb issue, after that take the car to a good electrical shop and see if the charging is proper. Usually if its fuse then the same side circuits will fail and not in diagonal.

To be on the safe side just check if all the grounding for wiring and holders and clips are in place also (DIY).

Looks like a freak bulb failure and again you might not have noticed the small marking bulbs going kaput earlier?

Its most probably a fuse issue. I had similar problem in my indica where LHS parking lights, rear lights, and number plate left side light went kaput.
On changing the fuse the problem went away, but again the lights went out. It was finally traced to a wiring issue. The coupler had a short.

I have no clue if the fuses are intact. The lights diagonally opposite seem to be not functional. I am going to the mechanic tomorrow to check the bulbs, wiring and alternator unit.

Since there is a pattern of functional (or non functional lights), I felt it could be a fuse problem.

Thanks for all your inputs.

Got the problem fixed today. No problems with alternator, bulbs and fuses. Some wiring problems fixed, not expensive. It sounded like hard labor though.
