Summary

My blockhead motors Wild One came with toyish yellow led buckets I did not like. I decided to replace them with cheap led light buckets found on amazon. They require to be mounted with a 2mm screw instead of the 3mm screws used by the one in the Tamiya kit. I put a picture of the led buckets for reference, they have a design allowing to lock the direction, with a second hole or something)

I designed parts to be able to fix and lock them properly with 2mm screws.
Each is designed with a bottom and a top part.

• The front ones don't require o-ring
• The bonnet ones use the standard o-ring inserted between the bodyshell and the top part and this will allow to lock the led bucket direction.

I also designed parts to add rear 5mm leds. They are here : https://www.thingiverse.com/thing:5147961

Have fun :)
