For months prior at night my low beams would dim and get brighter periodically. Then as I was driving one morning I began to smell an electrical burning smell. Luckily I was on my way home which was less than a half mile away. When I got home I opened the hood and saw smoke coming from the fuse box. I immediately disconnected the negative battery cable and proceeded to investigate what happened. Upon further investigation the hdm module had failed and was melted right into the fuse block. If I had driven any longer than I did I feel like my car would have certainly caught fire. Luckily I got home safe and prevented any further damage from my car.
