Hello, everyone, I am new to this forum. I am a product designer who is looking to get better at electronics. I have played with very basic electronic such as arduino etc. I have a basic understanding so far of electricity in term of physics . I am currently working on a personal project. I am basically trying to understand this circuit and how it works. I have, I think made an approximate diagram by following the tracks and do a list of the componants to find what they were. So basically this PCB came from an motorcycle headlight which has low and high beam. It must be a very simple device, but I really want to understand how it works and what does each componant does in tha particular circuit. I would greatly appreciate your help, thank you very much in advance.

my diagram (I might be wrong) HB is for High beam and LB for low beam

And here is the list of the componant I ve gatherd besed on the code number.
