High side switch for Car lights (50% Duty c.)

hi, i'll try short possible , on subject.

i've been trying while turn car lights on/off 50% duty cycle.
my car's lights turned on relay placed on high side and don't want change !

what tried:
circuit 1 (total fail, x2 mosfet fried)
mosfet:  fdd4243
transistor: 2n2222 , 2n3904




circuit 2 (first time success, don't know did , fried driver, then, instant fried one)



mosfet: irf5305pbf
driver: tc4426epa


my question is: circuit should try, driver should buy ?
i found high side p mosfet drivers on internet coudn't find them local

how current lamps take?

both these devices have rds on of 50mohms, 10a flowing dissipate 5w - without heatsink they'll fry!

choose 1 lower rds on - <10mohm.

and heatsink
