Ok so I have 2008 Slk55 with halogen lights. Lights are too dim for the rural areas. I can either upgrade to new factory xenon headlights and wire them or convert existing halogen lights with an hid kit. I need a new headlight housing either was but wasn’t sure which route to take. Def will stay away from the aftermarket headlight housing.
Give me some thoughts. I have always loved the brightness of good quality hids.
Any success stories?
On my 55, the dipped beam is xenon and the main beam is H7 halogen - and I believe this is standard. When I first got the car, the dipped beam were superb, but driving on unlit country roads was scary, and it was almost impossible to illuminate road signs at a reasonable distance ahead.
Very simple fix - I swapped the standard 55w halogens for 100w halogens. The difference is incredible, and because it's the main beam which is used for the 'flash' function, it gets noticed day and night... The other advantage is that now, the colour of the dipped and main are almost identical. The only caveat, I wouldn't leave them on for extended use, due to the extra heat produced, but in six years of ownership I've experienced no problems at all.
Another former 171 owning member who lived near me was also dissatisfied with his main beams. He opted for 80w bulbs and was very happy with the improvement. Having said that, when we removed his original 55w items they were heavily charred inside - significantly worsening their performance.
My two 100w bulbs were < Ł5 on Fleabay - which included two free blue 5w side/parking bulbs. All four are still going strong after 6 years. And yes, the standard wiring can handle the extra wattage, but I reiterate, I don't use my main beams constantly for more than a minute or two at a time.
