Finally got my lights sorted after much internet searching. Looked at the light options listed in the pages prior for the rear light. Light My Bricks wanted £35 just for the one rear light for the Bugatti!!!
In the end I took a gamble and purchased the base Lighting kit for the Bugatti from game of bricks. LEGO Bugatti Chiron 42083 Light Kit (gameofbricks.eu). With the GOB10 code knocked the whole lighting set to £16 delivered. 1 week later it arrived but it appeared the rear light strip was actually a strip of red leds behind the red tube. Doh! But I soldiered on and used the 8 single front light sets for the rear and am very pleased with the result :-)
Rears used all but 2 of the Bugatti front white lights and existing red tubes, LEDs fit straight in the red tube supports.
2 sets of the Bugatti rear light strips trimmed for the brake lights held on with tape
Engine bay I used the adhesive backed blue light set
Interior the adhesive backed white set
Front used the last 2 remaining Bugatti front white lights sat in the technic light pieces without adhesive.
To make the front look better I've ordered 2 more front LEDs but some how blagged these for free through misunderstanding emails and language barrier :-)
