I'll be going through with the euro light upgrade this coming spring after a brutal Canadian winter. I love the look of the euro lights along with increased safety that comes with the greater night vision. It is true what people say about taking 10 years off the look of a 124 or 201 series after taking out the substandard DOT lights and putting in the flush euros and clear side markers. The side markers will just add to the overall look of the new lights and bring increased safety during night time driving. I do know you'll need to coat the areas you punch through the sheet metal with silicone to protect against rust. Also take extra care when wiring and make sure your tapping into the indicator relay not the parking lamp relay. Good luck with everything!
