Our living room led’s will pulsate dim to bright and lasts for a while. Not sure what to check. Ant advise is appreciated

I would check the condition of your battery(ies) with a multimeter. Both plugged into shore power and unplugged from shore power. LED's are voltage sensitive. Post back what you find out.

I had a similar problem with the halogen lamps about our 3 year of ownership. The factory service center replaced the converter under warranty and problem solved. The converter voltage output was fluctuating.

I don't have the newer LED lights, I replaced the halogen bulbs in our 2013 36RL with LED bulbs, I found the pulsing is caused by one or more LED segments in the bulbs had failed and are going on and off. You may want to take off the cover and look. In my case the LED bulbs were the cheap ones, better quality ones didn't pulse.
