Hi Everyone

I just wanted to make a little review on a company I have used to purchase LED bulbs.
Horizon LEDs | LED Fog Bulbs | Buy Car LED Bulbs


I bought 2 of these in Amber
T20 - 7440/3156 : T20/7440 - CREE LED 5W
and 4 of these in red
T20 - 7443/3157 : T20/7443 - CREE LED 5W (RETRO)


I did have a few niggles with the indicator bulbs in that they needed a resistor to work. I started with the 10w, then 25w, then 50w. The guys at Horizonleds were great they swapped the resistors for me very quickly.

The 50w resistors will be what you need for a 2008 civic 2.2
50W LED Canbus Error Free - Load Resistor Kit

I do get a pgm-fi error from the brake lights but this goes away on its own after a few days. I have thought about getting another resistor for the brake lights but as the error goes away I'll wait.


Pics to follow soon [smilie=ebil-thumbu:

The resistor you need depends on the current draw of the LEDs you get.

Stock wattage draw-LED bulb wattage draw=wattage needed to be used
wattage needed to be used÷car voltage=current needed to draw
car voltage÷current needed to draw=LOAD RESISTOR OHM RATING.

An example using a 7.5w LED bulb
21w-7.5w=13.5w
13.5w÷14.3v=0.95Amps
14.3v÷0.95Amps=15.1Ω

You dont need a resistor for the brake lights at all.

The PGM-FI error you are getting is something else, a loose cable?

I have LED brakelights and have no issues what so ever.

I put the 50w resistor up as thats the one that worked with the 5w bulbs for me. I started off at 10w which caused hyper flashing, sent them back and tried 25w still hyper flashing but 50w work great.

The brake lights are the same 5w bulbs and are the cause of the error. If i switch them for normal bulbs the error goes away straight away but with them The error will show up on the dash for a few days then go away. It is still logged if you plug in a error code reader but least it doesnt show up on the dash.

It maybe something specific to the UK modules as the company have not seen these problems else where before.
