My old man has a Peugeot Eldiss and has done the following, ...."a bulb in the kitchen popped. It was 12volt 10watt. ..I replaced with 12volt 21watt much brighter but can it or will it cause any problems. ..seems to work well! !" If this is ok or a no no

It depends what the wire rating to the light is and also if the new bulb will cause issues heat-wise etc with the fitting/surrounding area. Are you walking halogen/normal bulb/LED?

As Minxy said.... Main issues.. Wiring not up to it and melting of fitting due to excess heat.
Put a daylight/white LED in if you want brighter.

I fitted an uprated bulb in a ceiling light. It got so hot it expanded the push on plastic ring that holds the glass in and smashed on the floor.

The problem is, the light fitting is designed for a 10 watt lamp. A 21 watt light will be twice as bright but will generate twice as much heat. The heat will build up and will probably cause damage over time.

The answer is an LED bulb - the nearest thing to a free lunch I've ever seen. Normal filament (halogen) lamps waste over 90% of their energy as heat. Non-halogen filament lamps are even worse. An LED lamp can produce the same amount of light with about a tenth of the wattage.
If you swap a 10 watt standard bulb for a 1 watt LED, the amount of light will be the same, but only a tenth of the heat. An even better choice would be a 2 watt LED, which gives twice the light for a fifth of the heat.

The downside is, they are more expensive, but they last a hundred times longer, so you'll probably never need to replace it.

And as well as all this, they are much less of a drain on the battery.

When you buy one, you may get the choice of 'warm white' and 'cool white'. Generally, warm white for lounge and bedroom, cool white for kitchen and working areas. But it's a personal preference. Warm white is just like a standard halogen lamp, cool white is more 'modern'.

I converted all the motorhome interior lamps to warm white LEDs four years ago, and they are all still working fine.
