I'm looking to replace all my 12v 10w cabin reading lamp light bulbs with new LEDs on my 2003 280 Sundancer. The bulbs I have now are the bi-pin/bi-prong type - I think they are halogen and get really hot - part number 858886 (I think). I'm looking to keep close to the brightness & feel of the existing light as I will be using them mostly for reading. Does anyone know where I can buy the new LEDs and what information is needed when ordering them, i.e., part number, lumens(?), etc. Thanks.
