I have Suzuki SX4-VXi Model

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.
