They are definialy brighter than the old stock ones.
TIP; After researching the inexpensive ebay halos on ebay and else where, one thing was suggested. Before you install them seal the glass rim, on the edges with RTV sealer to make sure there is an tight waterproof seal. Seems from the forums that leakage is an issure on these aftermarked H4's.
So when you first get them seal them where the glass meets the plastic.
I did and let them dry a day them installed them.
There was no wattage listed in the ebay add and nothing on the box or unit itself, so I am assuming they are just reg. wattage, but that still beats the old halogen stock headlights that had moisture in them also. What do you expect for 16 bucks plus shipping.
