Many manuf. use brass, Phillips uses nickel plated...no diff...and if you cross the numbers, it's still an 1156/7!

Use anti-corrosive paste* to keep either type from growing greenstuff!

Halogens lamps are OK, but do not up the taillight lamp wattage the increased heat will melt lenses....also brake light switch will not survive...LEDS MAY be an improvement, but its NOT guaranteed! Do tests!

Jim;

I you had used two of the brass base bulbs from the same manufacturer, I bet a hot fudge sundae the lamp-out indicator would have been satisfied too and stayed OFF!

Lamp-out indicators work by balancing magnetic fields produced by right and left side currents against each other to cancel. When new, lamps are guaranteed from the same manuf. and even batch, replacing a lamp later with one which is not from the same manufacturer as the other means there may be a slight, but significant diff in the right and left side currents...and the magnetic sensors are sensitive enough to pick this up and trigger the warning light. On vehicles, with Lamp out sensors, lamps should be replaced in pairs to avoid this...

You are entitled to you opinion, but I personally don't see a noticeble difference in quality between nickel plated and brass based lamps...but corrosion will occur on both and stop them both from working!

Cheers
