• Endurance Voltage Range: 10~18V

• LED current regulator added (What it is?)

• LED Type: 5050 SMD 3 Chips in one LED (What it is?)  Many sellers don’t even understand!(LED Type General Classification)

• 7443/7440/1156/1157 can be ordered by customer's demand as well

• Nos. of LED: 13PCS(39 Chips) TOP:6 PCS; SIDE: 1 PCS x 7 STICKs

  There are too many SMD LED made auto bulbs @Ebay, however,  why 5050 type is now the well-known most suitable to use in LED BULB?

  YOU HAVE TO KNOW this Number of  5050, 1210...etc. is named by its size

  YOU HAVE TO KNOW 5050 IS THE BIGGEST ONE TO BE MOUNTED IN 3 LED CHIPS INSIDE, AND ONLY 1 CHIP FOR 1210 & 1206

  YOU HAVE TO KNOW YOU CANNOT JUDGE THE BRIGHTNESS BY LED QTY BUT LED CHIPS QTY, DO NOT BE LIED BY SOME SELLERS WHO DO NOT TELL U THE TRUTH

  eg. 10pcs 5050 SMD =30 Chips, 20pcs 1210 SMD=20 chips only! 

   YOU HAVE TO KNOW THAT SMD LED IS BETTER THAN HIGH POWER LED IN HEAT RESISTANCE PERFORMANCE  & HAS LONGER LIFE

  　

• NOTICE IN AUTO LED BULB :

DASH BOARD ERROR MESSAGE--

Please be advice that many modern luxury cars which computer built in such as Mercedes Benz, BMW,. etc., have sensors built into the dashboard computer system that can detect if light bulb works. However the purpose to use LED BULB is energy saving, which means the car computer will misjudge the LED BULB not work because of the low wattage to lead the error signal showed in your dashboard. Basically the bulb can be judged OK when the wattage goes up to 5 Watt and above, all LED BULBs themselves have nothing to do with this problem except you install resistor to enlarge the wattage

FLASH SPEED FOR SIGNAL/TURN LIGHT APPLICATION--

Normally when you flip your turn signal switch, the light blinks at a set, slow pace. However, if you have modified your lights to use LEDs, you'll notice that the turn signals now blink very quickly. This is caused by the low resistance of the LEDs due to the fact that they use less energy. To correct the problem, you'll need to wire the turn signals in a parallel circuit. To do this, you'll be installing a resistor or control flasher.
