The light gets brighter because the higher crank speed is generating more electricity. Your battery is getting weak. Check to see that water covers the top of the plates in each battery cell. A strong battery will make up the difference at idle speeds. Most bike batteries will only last two years or so. Please rate my answer. Thanks.

Lights go dim when rev engine

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

Headlights light go dim and normal at night driving,even the instrument panel goes dim at the same time.

You might want to check your car battery as this might be the reason. Otherwise maybe you might have to replace your altenator.

I'd definitely check battery and battery cables. In the past, I had a vehicle where the lights at night would brighten and dim a little on their own, drove me crazy, at the moment, I can't remember if battery or battery cables, one or the other. Just my opinion.

the idle is controlled by the computer and the idle speed motor if the idle is too low the first thing you should do is check for a vacume leak as this will directly effect the idle or revs as you say
