Simple how to: Upgrade side light bulbs w/ LEDs (Ford Mondeo Mk3)

Old 5W 501 wedge bulbs are a sickly yellow color. Here's how to select a bright white LED of the correct configuration, and replace the side light bulbs in your headlights.

You will need:
Replacement T10 / W5W / 501 LED bulbs, white, forward firing*
Long nose pliers

The LEDs featured turned out to be unreliable. I now recommend for this application the Osram bulbs reviewed here:    • Review: Osram/Sylvania LEDriving W5W ...

The car featured is a Ford Mondeo Mk3. European cars typically have these white corner lights, as opposed to American amber side lights. If you want to replace bulbs in amber fittings, be sure to choose amber colored LEDs, not white.
