I know a lot about mechanics but electricity scared me so i need community help

i dont have any headlight nor taillight for my honda fourtrax 300 4×4 1995

i have bought new bulb , but nothing work , i check the wire that i saw underneath the fender near the headlight and every wires looks ok , and the handlebar switch seems to work because the starter and the on/off button work , i have a multimeter but im not sure where to check for current and dont want to blow something else , is there fuses especially for the lights ? , can i check voltage in the connectors just before the headlights , which color to check , you probably see that i’m totally lost in that domain , so if you please help me precisely on that would be grateful

thank you all
