Use 70W High Wattage H7 Bulb in Place of OE 55W?

Yangorang · 12-13-2019, 12:43 AM

Has anyone tried using 70W high wattage bulbs in place of the standard 55W ones in an E90? Any codes or issues with this? I would think the stock wiring should be able to handle the modest power increase, and it shouldn't be so bright as to be totally blinding.

I wouldn't, you'll likely burn the housing plus there are far better upgrades in the LED and HID world.

Also isn't the output to the bulbs current limited to avoid shorting the controller?

Would the extra 15w be enough to ruin the ballast over time?
