You should look into these for building lights. Better yet, just buy one ready to use and quit wasting your time with all these novelty 12 V automotive aftermarket LED devices.
The high powered LEDs I'm using are also designed around lithium cells. So is the electric bike I'm driving. Interestly enough - neither one is 3.7V. The lights aren't considered novelty items as they were in use by NASA before there were LED bike lights. But thanks for your opinion.
