Spotlight replacement bulbs

mikebs

I have an Autocruise Starspirit and I would like to change the spotlight halogen bulbs to LED. I have identified what I think is the correct replacement, a MR11.

The halogen bulb has measurements of 35mm dia and 30mm depth including the pins. 

All the led bulbs I have viewed on line have longer depth and therefore seem unsuitable. Has anybody changed to LED on their Autocruise or can recommend a suitable product.

Thanks.

Mike
