Interior lights going crazy

Check your fuses for starters

Your headlight switch is shorting to you blinker switch or vise versa. This effects the interior lights because the dimmer switch is wired with the headlight switch. Both switches will need to be rewired. For a car that's less than 10 years old that is ridiculous. You could try to lodge a complaint with Honda. Most cars don't have issues like that for at least 20 years. So unless you've been driving through the arctic or have 500,000 miles you should not be impressed.

check the headlights auto unit for a malfunction

a. Your Light Switch on the Dash has gone bad....
b. It became Unplugged

More than likely, your Switch actually went bad...

Interior lights check for a blowin fuse, For the signal lights end hazzard lights,Get a new signel light flasher, End try it,, If that dooesn,t work there could be loose wires or a brek in the wires or that there is a short some where in the wireing, That will have to be check out at a auto electric shop,

Check the interior dim switch. When it is set on daytime mode (the setting right below highest solid circle) it can sometimes get loose and turn on the interior lights. Try leaving it on the setting right below time mode where it is a little dim, but manageable. Hope that helps.

replace multi funtion switch on the colum (turn sig.switch)u can prabally mess with it and get then to flash just a bit

check your fuses

I would have the headlight switch checked. Interior lights take their power from the headlight switch.

check the headlight relays under the hood also fuses under the hood and in the interior fuse pannel.
