Review on Philips 4157NA Long-lasting Miniature Bulb, Pack of 2 by Devin Maselli

I replaced an OEM Sylvania 4157NAK with this bulb (front turn signal/running light on a 2008 Tundra). After a few weeks I noticed that it looks yellow-white instead of amber. I tested it and found it worked so hard that it started melting the base of the bulb and apparently burned off most of the amber color. Well... maybe there is something wrong with my truck or I need the "K" (Krypton) version. I replaced this Phillips product with an Eiko 4157NAK. I will unsubscribe if I have any issues with it suggesting this is my truck and not a lightbulb. EDIT: I had the same problem with an Eiko lightbulb. It turned out that the socket was bad. After replacing the outlet, everything works fine. I'm changing my rating to 5 stars because I have no reason to believe the bulb was the problem.
