Sorry for back to back post.
But I have to mention that the mod is now a 100% success.
Managed to remove red fog reflector and lens from the enclosure using pliers (pakkad). Took 15 min to twist and break it inside and pull it out piece by piece. That took care of reverse light.
Went to a local paint shop and did a red tint on the yellow fog bulb.
Also need to make sure that a pin from both the connector sockets need to be swapped from 5th to 6th holes and vice versa. If not sure go to your local workshop and ask them to add a tether wire. Do not cut any wires at any cost.
So the mod is possible I can confirm. Whoever wants to buy, I can help.
