Yes, you are right, the mudguard I received from Pacific Cycles for my Titanium Birdy do not have the rear reflector like the one mounted by R&M on my Birdy 3.
It won't be easy to have them in Singapore, the only online shops I know do not ship outside EU. But you could try

For the dynamo front hub, its a special type from Shutter Precision with the Birdy disc proprietary disc mounting position, its possible to buy it online in Asia. You can then build your own front wheel with a matched rim (the Pacific Cycles Birdy do not all have the same Alex Crostini rims mounted by R&M on the EU Birdy).
For the front light, its an old model from Supernova not very powerful, Its still sold by Supernova but the LED used inside are now obsolete. The rear light is specific to Supernova, it works only with a Supernova front light. You would be better with a SON Edelux 2 front and BUMM My rear (or the Supernova M99 DY Pro).
