Headlight slightly dimming when indicators on

[beefjerky]

Hi!

I've noticed that the headlight dims very slightly as the indicator flashes.

I dont know if it always did this (only riding 2 weeks, this 2000 gz is my 1st bike)

I put a new battery in the bike 2 weeks ago, now, I dont have a meter to test volts or anything but is there any manual or visual checks i can do OR is this normal?!

Thanks!
