Vintage BMW Motorcycle Owners

I rode last night with a friend accompanied me for several kilometers.
This morning he called and said it wouldn't hurt for me to improve the rear light a little, because "he's already seen better ones". Is there a LED or halogen bulb (or any other solution you say) that will fit the rear light housing?
I run a 12 volt PowerDynamo alternator system and the current bulb has two filaments, as I have a brake light.
I'm looking for a plug & play bulb that is available at Amazon, eBay etc.
Thanks!

I have bought two led plunger frame type small round taillights. The first I bought from Bench Mark Works & the second from Max BMW parts. The taillights work amazing. I have a Motoraad Electric 12 volt alternator on both bikes. As you can imagine they are super bright. Modifying the original taillight was easy.
