    Hi, i am upgrading my front headlights to facelift hella angel eyes. My current bulbs are hb4/9006 51w (dipped beam) and hb3/9005 60w (main beam). The new bulbs are both H7 55w. My question is would this slight difference in wattage bring up obc warnings?
    Many thanks.
    Jason.

    afaik the obc checks bulbs for continuity...any high resistances flag up the warning,so you should be fine
    what i've felt,what i've known
    never shined through in what i've shown.
