brake & front light issue Options

[JFG]

i have the euro light set up on the front of my car but i found an issue today.

all lights work normally on the exterior independently. today i saw my front side lights illuminate when i press the brake pedal, the brake lights come on also .
the only other quirk i have is that when i indicate left or right the 2 arrows on tje gauge flash once then stop but outside lights work as normal. these arrows work when i use the hazard flashers.

if i remember correctly i used a diagram from jeff bowlsby website for the wiring and i'm sure this has only just started as i've checked my lights numerous times

I agree with what Dave said about the brake bulbs. Also try removing the brake lights and see if the front lights come on. Is it only the front sidemarkers or all front lights (left and right).

About the indicator arrows, both flashing when the L or R turnsignal is selected is a weakening of the secondary coil in the flasher relay. A new flasher relay will solve this.
