Hi Martin, i swopped ordinary bulbs for led's on my car ,same bayonet fitting as the originals but a lot brighter but i was getting a 'bulb' out warning light on the dash due to the lower resistance of the leds, it was a simple fix though just had to fit a resistor gizmo into the rear light cluster.
not being a techy type not sure whether or not the same would apply to your kon-tiki.
got my led's and the resistor gadgy off fleabay ( led bulbs were about £14.00 a pair the ristor kit was under a fiver) , but i'm sure you can get led bulbs with a built-in resistor though
