| We replaced the factory bulbs in this ML 320 with ones from HIPER INDUSTRIES. H7 size was used for the low beams and H1s were used for the high beams. Installation time was under 10 minutes for all 4 bulbs. Since this article was written, we have installed 80 watt versions of the H7 bulbs and have been driven at least 3000 miles with no ill effects. (but at
your own risk!) |
