Simple plug-n-play bulbs???

[ds06nomad]

OK, I need definitive answers to what is probably a SIMPLE question:

I have a 2006 Nomad 1600. I have the stock lightbar and all stock light bulbs in the entire bike. I would like to get brighter (LED?) bulbs in any/all of the following places on the bike:
1. Brake light: is there a LED bulb that I can simply remove the brakelight cover, remove the stock bulb, plug in the new LED bulb and reassemble without having to alter the existing electrical lines?;

2. Headlight bulb: (same question as above); and

3. Spotlight bulbs: (same question as above).

Has anybody else done simple upgrades to the stock bulbs that DON'T require messing with the electrical lines at all? If you could tell me the EXACT bulbs I need to get for each application, I'd really appreciate it!

Many thanks!
