Is it possible to replace GU4 halogen light bulbs (on a 12v lighting systm on a narrowboat) with LED bulbs of the same size wihout the need for any other equipment i.e. LED drivers/transformer?

Dear Mrs Palin, Some LED bulbs are now available with mains input, these would obviously not work on 12v DC. Other 12v DC LED bulbs are sold for use at home paired with a suitable driver/transformer. These probably would work on a boat without the driver but very likely only for a very short time. Others, specifically marketed for boats, have the driver/surge suppressor built into the unit and these should work well. Every time any motor or other appliance with a coil inside it turns on or off a significant voltage surge is likely to be applied to the boat's supply and although it is over very quickly it is known that these surges damage electronic equipment that is not designed to cope with them like simple 12v LED lamps. Have a look at the Automotive LED Bulbs on http://www.bedazzled.uk.com/12v_LED_Bulb_Replace ment.htm
