No, that ain't normal. Battery must be getting weak, go to a parts store and get it tested.

It could also be a poor earth connection between battery and chassis (high resistance causes volt drop; the more current drawn, the bigger the drop, the dimmer the lights, etc). Just clean it up and grease with vaseline or similar.<p>If it happens when the revs are high, it also suggests the alternator output could be below par.

It may not be your battery at all It could be the altnator as well.

my grandfather and father run a lead-acid battery store. specialize in auto batteries and ignition electronics. Obviously I have grown up around there and work there. Here's the deal. Alternator. It COULD be the ground like suggested a few replies earlier, but I have never seen that happen. But it is still feasible. Any battery store or garage (not auto parts store) will test your battery AND your alternator! So do that. But I would bet my favorite coffee mug it's the alternator. I've just seen it too much NOT to think so.........
