One of my hid ballasts gave up so i put my standard h4 bulbs back in till after xmas and my word they are absolutely cack. Ive noticed most cars with h4 bulbs are the same but ive noticed that two other vehicles in my house have H7 bulbs fitted and they are so much brighter and light the road more. Went to the takeaway at work last night in a colleugues car with him(vauxhall vectra) and his standard H7 bulbs light up the road so much, its like mine are turned off in comparison :/

Replaced mine with halfords extreme brilliance yesterday. Makes a huge difference

My bulbs are shocking

No idea what fitment they are but they are pretty lehal
