Any ideas where I can buy Multi Colour change LED bulbs (E27 or E14 connections) and LED Christmas Lights or Rope Wholesale in BKK?

They don't need to of quality as they only need to work between now and New Year. (Seasonal Shop Decoration)

I am guessing China Town?, but if anyone can recommend a specific shop that would help.

Thanks

Baan Mor in China town (in Bangkok) has lots of shops selling these ..

Forgot to add as there are so many the wholesale price changes all the time, so best to go and pck a shop where you get (1) service (2) design build [if needed] (3) ongoing support. Believe it or not Amorn has some really good prices all over the country.

Go to the old Siam mall in Chinatown, take the exit at the Mac Donalds, cross the street and walk straight into that soi. Look left and right for small alleys because there are plenty small shops. The whole neighbourhood there sells them.

That is Baan Mor .. same place but you described it better ..
