These are what I am looking to change to:
1157 LED Bulb - Dual Intensity 1 x 3 Watt High Power LED w/ Reflector Lens | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Bulbs | Super Bright LEDs
or:
1157 LED Bulb - Dual Intensity 1 Watt LED w/ Stock Cover | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Bulbs | Super Bright LEDs
And of course the 1156 version for the rear directionals.
I do not have a part number yet, but I am told there is a replacement socket that will fit in place of the stock one from Land Rover. I do not know if it has the plug on the end for easy connection or if this will need to be removed from the stock units and added to the rover parts.
The reason for selecting these specific bulb styles (and I am leaning toward the first) is the fit as many are too large for the overall housing and depth of the socket.
These use quite a bit less power than a standard 1157 bulb which uses 8.3 watts for the low element and 26.8 watts on the high element, so the wiring is not an issue at only 3 watts.
Hope this helps,
Julian
