If it stayed on then you'd have an issue. Quote Share this post Link to post Share on other sites

JaseNZ 53 Report post Posted March 25, 2011 Could be your dimmer switch is set low, This dimmer switch also does your dash lights etc. It could also be one of your lights out on the obc , its quite common they need replacing. Quote Share this post Link to post Share on other sites
