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.

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.........
