I have suzuki SX4-VXi Model. recently i changed the headlight lamps to 90/100 watt as original 55/60 watt have poor illumination. lamp replacement job is done by auo-electrician. for this job he used roots relay kit with wiring harness. he made some changes and joints in the existing wiring. after that I started facing problem of fuse blowing for high beam only when I drive either in the night or day by operating high-low (upper-dipper signal for front vehicle while overtaking or vice versa) beam switch for 10 -15 times approx. The fuses of 20amps to 40amps rating were used but the problem is same. one time one auto-electrician bypass the high beam fuse and you know what happened? both high beam lamps fused at the same time after operating upper-deeper switch. and for your information when original 55/60 watt lamps used there is no problem of fuse blowing. pls. tell me what would be the possibilities.
