Don't worry about the K. That means that the original bulb was a long life (krypton filled) bulb. Has nothing to do with its function. The rest of what you are asking...I'm confused about: " i have power at my tail lights but not the front". So do this mean that you don't have any power to the front at all or just that the bulbs don't light-up? You already tried flipping the bulbs over right? Some leds only work when plugged in to correct polarity (negative and positives line up). Pull the bulbs out and test them with a 12volt battery source to make sure they are not shot and to find out if they are polarized. Hope this helps.

No LED light will melt housings. They produce a lot less heat than incandescent bulbs. If an incandescent bulb won't bother it, an LED bulb sure won't. I have them in my DRLs in my '04 and haven't had any problems.

bbrown wrote:So I decided to convert all my bulbs (this topic deals with turn signals only) to LEDs and I knew the flasher module would need swapping; so I did that and there are no issues with flash rate. The issue I'm having is with the turn signal indicators in the dash cluster. Whenever the headlights or parking lights are ON the turn signal indicators stay on constantly. This doesn't happen when the lights are off; the signal indicators behave normally then. So, finally my question: Is there any way to make the indicators work properly without installing resistors? I know the LEDs have much less resistance than the incandescent bulbs but the LEDs do light up and blink as if there is no problem at all. I've just got to solve this signal indicator issue. Thanks in advance for any help. Oh, and if I do need resistors; no other option; how many ohms do they need to be? Bulbs are 3157s.

Cheers!

I noticed that you solved your problem but I was going to suggest pulling out the LED bulbs, rotating them 180 degrees, and putting them back in. I remember when I installed my LEDs, I was testing them and one of my turn signal lights stayed on constantly and the other flashed quickly. I rotated them both 180 degrees and they switched. So then I made it where they both now flash quickly. I need to get some resistors now I guess so that they don't do that.

To solve quick flash, I'd recommend the electronic flasher unit replacement. The load resistors just increase the ohm resistance to fool you old thermal flasher so it's a band-aid at best. The flasher is the better choice. That way your actually seeing the benefit of lower power consumption of the LED bulbs. The flasher modules can be found at most of the chain auto parts stores for about $12 and you only need one that matches the current flasher blade configuration. The resistors are needed for each LED bulb and if the resistance isn't right the flasher will still act wacky.

where did you get the LEDs for the DRL and what size did you use

I found the size from Sylvania's guide and then looked on eBay. I have the 03-06 body style, but I'm pretty sure the 99-02 are the same. The turn signal and DRL bulb size is 3157. Also keep in mind that some other bulb sizes will still fit, I know 3057 and 4157 will.

I ended up wiring in resistors on the flasher circuits right at each front bulb. That fixed the problem. I running all LED lights except headlights, fogs, and DRLs.

bbrown I am having the same problem that you had with the indicator. What did you do exactly to fix this problem?

bbrown · by **bbrown** [OP] » Feb 25 2012, 7:11pm

Well, two things actually. The electronic flasher solved the flashing rate for starters, then I added the load balancers to the front circuits to solve the dash indicator issue.

bbrown · by **bbrown** [OP] » Feb 25 2012, 9:07pm

Just to be a little more specific (was in a rush earlier), you can find the load balancers/resistors at Auotzone or Advanced and you splice them in at the bulb or just behind the front signal light housing. You want to tap them into the flasher circuit only not the parking light constant power. On my truck, I tapped the brown and black wires and the load resistor is connected across. That way, the resistor only affects the flasher circuit and not the parking light power. Hope this helps.
