Two wire flasher module teardown with unexpected find

This was such a pleasure to reverse engineer because of the unexpected hybrid circuitry that uses a very retro component to control a modern one. And bizarrely, the "retro" component is in a modern surface mount package. A search on Aliexpress found an SMD transistor called P27 which may be a modern variant of the 2N6027.

The module is mainly intended to replace traditional indicator flasher relays on cars and trucks with low current LED lights. That said, a parallel resistor may be required across some LED lights to ensure proper operation. 1K (1000 ohms) should be ideal.
