Why I have these problems?(melted bulb base, blow fuse, blink like a strobe light etc..)
This is happening cuase your vehicle is not compatible with LED bulbs(low current draw) few customers do have these problems. Don't worry, you can easily solve these problem by adding load resistor, load equalizer or electronic LED flasher. (Auto Zone, Kragen,Pepboy,Radio Shack or any auto part stores might have it.
Turn signal issues with LED bulbs(hyper flash or won't flash)
LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. These installations will require an electronic flasher unit, available on ebay or at any auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.
Another fix is the installation of Load Resistors which are wired across (in parallel with) the turn signal bulbs to simulate the load of a standard filament bulb.
Dash indicators reporting burnt out bulbs
LED bulbs may cause some newer vehicles to indicate a bulb is burnt out (because of their low power consumption). Some cars indicate this by increasing the flash rate of the turn signals, some turn on a bad bulb indicator. The only fix for this is to install Load Resistors across the bulbs that are being indicated as bad. Some vehicles will also disable the cruise control system if a brake light bulb is being indicated as bad, the installation of Load Resistors will also solve this problem.
If I install LED bulbs in the dash, will the dimmer still work?
Yes, LED bulbs will dim with your dash light intensity control.
ELECTRONIC LED FLASHERS
You should definitely use one of these instead of Load Resistors cause they operate at the correct flash rate with LED or standard filament bulbs 10~15 Volts DC - Flash Rate: 80 per minute
Note that some of these flashers operate silently, they do not make the familiar clicking sound when operating. One solution is to connect a common automotive relay to the output along with your LED bulbs
Also note that these flashers do not replace all flasher units. Before you order, please see the pin outs of our flashers in the table below and compare with the one you are replacing. Click the part numbers for complete spec sheets. You can usually find your flasher pin out printed right on your flasher. Failure to check this and installation in an incompatible vehicle can blow your fuse, destroy the flasher and void the flasher warranty
2-Pin and 3-Pin (1/4 inch spade lug type) LED compatible Flasher Units
LOAD RESISTOR KITS - one load resistor is required for each turn signal bulb
6 Ohm, 50 Watt resistors can be connected across the turn signal bulbs to simulate the load of a regular filament bulb (2 Amp load). This will solve LED related turn signal problems such as hyper flashing or burnt out bulb indications. Resistor measures 1.96L x .64W x .60H inches, leads are 12 inches long.
Kit Includes gel filled moisture resistant splice taps.
CONNECTION INSTRUCTIONS: Using included splice taps, connect one wire to ground and the other wire to the turn/brake hot wire. Splice taps allow for installation without cutting your turn signal wires.
25 Ohm, 25 Watt Load Resistor kits which can be used with LED side marker lights (194/168 type) to prevent bulb-out indicators from turning on.
