I don't know why, but I have a feeling your making the purchasing and fitting of an led festoon bulb sound alot more complicated than it really is.
Incase u havent noticed Im a GIRL I don't know what a headsink or a diffuser even is. Do u know how frustrating it is to ask the same question 3 times and never get a simple straight answer? I'm sure alot of people go out to Jaycar or supercheap or JB Hi-Fi and they buy an led bulb that pops into their light fitting and works just fine and not havta worry about it burning the car down.
I would have just loved for one of you to tell me something like "Hey, just make sure you buy something 2W and up, u can usually pick them up at this place for about $6." or "I used this bulb in my corsair/pintara and it worked fine, I bought it here" It'd especially would have been cool if someone told me why my dickies led might not have worked in one car but worked in another. For all I know I had it the wrong way around, but no one thought of that did they. You start offering me tedious and probly expensive solutions like "Try getting hold of a Luxeon 5W LED Globe" instead of looking at why the one I just bought didnt work & what specifications might I need when I buy the next one, rather than only one specific brand that I could look all over brisbane for. Most you guys would own a similar car, you must know what to look for.
Anyway, I'm sure when I go to Jaycar in the morning, they'll explain why the dickies one didnt work, they'll give me a simple led or even just a globe that'll work fine in my car and I'll leave the dickies one in the bf's car.
I was just kinda hoping you guys could offer me some advice on why my dickies one didn't work and what I could try to get it working since I'd made the effort to go out and get it, but I guess that was too much to ask...
