Just finished reading most of the posts here and had a couple questions.
Can someone explain what hyperflash is? Also is there any real difference between 7440 and 7443 and what is that difference?
I agree with those concerned with brightness, a lot of LEDs are entirely too bright. Same goes for interior bulbs. nothing worse than opening your door at night and being blinded by your map lights. Not to mention if you actually needed to used them as map lights (not that anyone uses maps anymore, but rather to use them while driving), forget it, they'll blind you and cause glare on the interior of you windshield.
Has anyone used any of the more well known brands (Philips/Osram/Sylvania)? If so please list the bulb you've tried.
I'm no wiz bang at this stuff by any stretch of the imagination, I know enough to be dangerous and hopefully keep myself out of trouble. My simple understanding of hyperflash is just what it sounds like. When a LED is hyperflashing, it's blinking at a very high rate somewhat like a strobe light. The cause of hyperflash is because there is not a resistor in line within the system to control the flash rate. We've all seen them on the streets I'm sure, the kid driving a beater whom wants to look cool so they install LEDs and you see the blinkers going bonkers when they use them. Been there done that in my youth but with 60 series tires jacked up on a beat to death '69 Mustang - but I was cool!
I literally just got done installing front and rear LED signals from Lasfit today. Just my luck each LED I installed was installed incorrectly. By that I mean with the LED installed either the front and or rear plus the mirror LED would hyperflash. Take the LED out and turn it 180 reinstall it to correct "polarity" for better lack of terms and the LED worked correctly with the proper flash rate, easy peasy . The rear bulb in the Passport is a single filament incandescent. The 7440 configuration is a single filament configuration for an LED. The front bulbs on the PP are a double filament incandescent, and the 7443 are a double filament configuration for an LED. Could a 7440 work in the front? Maybe but I went with Lasfit recommend.
I can't vouch for the brands you mentioned with regards to LEDs though they are some of the more know manufacturers in tradition lighting. Remember cheaper pricing on LEDs generally mean they don't have built in resistors and will hyperflash, which will require the purchase of an in line resistor for each LED installed. Lasfit LEDs have built in resistors for a cleaner and much easier installation. Their website explains this better than I could ever do.
