odometer is slightly pulsing with certain bass lines?

[okiestylin]

My little led that displays my odometer is slightly pulsing with the bass... my headlights have NO dim however...I have big 3 done under the hood plus an upgraded interstate deep cell battery with a 1200 watt amp? Is this ok as long as there is no headlight dimming? Only seems to do it on punchy bass lines..Any input is welcome. Thank you.

Check ground, if it's good back off the gain just a bit.
