I would try a fan or other 12 v gadget when the pump is running to see if you can determine any fluctuation in it. If you do, it's likely the pump motor failing or intermittently shorting, causing power fluctuations. As far as I know LED's either work or don't but can be dimmed with lower power levels. Maybe someone else has been there, done that and has a definitive answer.
