turn signals on regular switch's

ok here is what i am doing , i am building a offroad and on road use vehicle and i want to wire the turn signals on regular switch's and eleminate the use of a steering column type turn switch............. basicly 2 rocker style switch's one for left one for right and i am running 3 wire led lights ( ground , running/parking lights and brake/turn  ) so i need to figure out how to wire it so that it cancels the brake light on the side that the turn signal is turned on , on.      if i have left turn signal on the left brake light is cancelled and vise vursa for the right .............. so does anyone have a clue on how i can do this i am tired of the cheep aftermarket turn switchs burning out from corosion.

i would do it like this. you wont need separate brake circuits, but you will need 2 relays. also the flasher has to be an led flasher because an led wont draw enough current to activate a thermal flasher. also instead of using 2 rocker switches, i would use 1 that was 2 position with an input pin in the center and an output pin on each outer end that would go to the relays. that way you could do something like......... up is the left side, and down is the right, or vise versa and only need one switch.

ok that looks like it should work right there but 1 question i see there is diode iso. , what type should be used?

ok i used the diagram , but i was unable to find anyone who had the 1n4001/L diode but i used what i had a 1n4002 and i wasnt able to find a led relay at any autoparts store but i found out that a 232 heavy duty electronic from oriely's will do the job and BINGO every thing works great ....... going to add this to my book of diagrams

Thank you for all your help.
