I'd be cautious. There has been discussion threads about how having the "wrong" light bulbs in the taillights can lead to problems with the cruise control, etc. I don't know for certain if thats been debunked or proven, but I've replaced my lamps with the correct ones, though I've also been tempted with the LED ones.

I know that the old fashion mechanical relays that are used with standard bulbs for turn/hazards can sometimes have problems with the LED ones, as they don't draw enough juice.

I have. Led bulbs in our housing suck!! The way the break bulb is positioned in the housings doesn't allow the led bulbs to work correctly. Plus, in most cases they really aren't even brighter than the incandescents to begin with. Put some Polarg hiper whites in and call it a day.

Has anyone ever tried using this on their W126s. http://cgi.ebay.com/ebaymotors/360-...635626036QQcategoryZ35598QQrdZ1QQcmdZViewItem


I'm very interested because i've actually felt that our brake lights are rather dim under the hot sun.

Advice needed!

Thanks in advance


Hi Joe.. Unless your an Electrical or Mechanical Engineer & your smarter then the Germans Engineers that designed these Metal Wonders..I'd just make sure that YOU got the CORRECT BULBS that those German Engineers recommended.

Good Luck.:D :D :D :D :D :D :D :D :D

LED bulbs - HEAT issues

Joe,

I tried using the LED lights and if my experience is anything to go by, it is not a good idea.

I first put clear corners on the car and thought the orange bulb ruined the "clean" look of my white car with clear corners. While I was at it, i replced the brake lights and the back-up lights with LEDs as well.

The first problem is that the car's "Bulb-out" warning lamp will light up as the LEDs don't draw enough current. The warning system uses to current draw to sense if there is a bulb present. Not enough current draw and the system thinks the bulb is out. This issue can be alleviated by connecting a resistor in paralell to the bulb, but it is a messy solution.

The other problem is that the light relays overheat, which can cause all sorts of issues in the fuse box and adversely affect other electrical componenets. I don't know if the resistors solve this problem too, but I was not going to experiment any further with my car and switched back to standard bulbs.

I got a set of "silver" coated amber bulbs for my corner lights and that works for me.

Hope this helps.
