Yar they draw almost double the current as the normal 55W bulbs. 90W at 12 V amounts to 8 ampere. That is a LOT of DC !!! many have reported thay their bulbs got fused and related issues. Some have also reported cracked head lights due to overheating.
Just browse pw and do some googling you will come to know. Anyway best of luck for the experiment. Keep the stock bulbs with you, you might need them again
