H4 9003 HB2 LED Headlight Bulbs 4-Side Chips 100W Car Auto High Low Beam Headlamp Bulb 6000K White Super Bright, 5 Year Warranty

Works well on SLK 250 CDI W172. Makes a big difference compared to original halogen bulbs. Used on dipped beams only. Very easy to fit, as the plastic location flange is removable from bulb body. After the simple task of fitting the flange, the bulb body is slotted back through the flange, and rotated 90 degrees to secure it in place. You will need to replace the headlight plastic dust cover, as the body of the bulb protrudes through the headlamp rear. I used "Eyourlife" Headlight Dust Seal Universal Covers, which cost £6.73 per pair from Amazon.

As these were four side I expected better light dispersal but there is poor forward lighting and dark spots all around. I'm very disappointed in these. The cheap and old halogens produced better light than these.

Thanks

Ok not as bright as I thought they’d be and one of the plastic sleeve tabs broke when fitting so now it’s not secure

On time...plug and play as it say

Great light and exactly what I was looking for brilliant light like no other like that I have tried. Will be order alot more of them.
