HERCOO Ice Blue LED Light Bulbs for Instrument Gauge Cluster Speedometer Compatible with 2002-2006 Dodge Ram 1500 2500 3500

Ignore the reviews that refer to half of the bulbs not working. These people clearly didn't read the directions (and have no fundamental knowledge of electrical polarity). The Amazon listing AND the directions on the pack CLEARLY state you should reverse any nonfunctional diodes. My pack contained 12 bulbs (11 for dash + 1 extra) and all 12 worked flawlessly. I installed them all, then plugged the cluster in. Only 4 illuminated. The white harness on the left (which feeds power to the lights) is long enough that I was able to spin it out the drivers door and reverse the non-illuminated bulbs polarities while the board was still hot to confirm they work as soon as the connection was made. Easy as pie. The whole thing took a grand total of maybe 20 minutes including disassembly and reassembly of the dash. Definitely buy this pack. I can't believe I allowed myself to drive around for years with a half burnt out, dim cluster. These new ones make the truck look 10 years younger. Much brighter, but still dimmable, it's the perfect solution. I got the white LEDs and just like the listing says, they have a slight blue tint to them as they shine through the gauges, but it looks really, really nice.

Light quality is better than stock. Fits like OEM, functional is a lot better than stock bulbs. Value for money is worth it.

My 14 yo installed them for me and they look awesome

Great product, looks amazing, and works as designed... Two things, First if you are not mechanical wouldn't recommend if you are you will have no problems. Second, remember LED's are diodes and only work one way. Do not put anything back together just plug in and check which light up. If you can not see back of cluster mark front gauge areas with pieces of masking tape. Then remove and flip LED 180° recommend testing and checking a couple of times before full install.

Looks great and fresh style. Must do trial and error for correct bulb orientation to get lights to work. Rotate 180 to get correct polarity. Took several installs and removal of cluster to test lights. I was also shorted one led bulb and had to leave one old bulb in.

Initially I was impressed with these lights after installing them in my 09 dodge ram. They were bright and made the dash look better. 68 days after installing, they are flickering on and off at times, or they just don’t turn on at all. To double check, i reinstalled the factory bulbs and everything worked fine. Put these LEDs back in, and same thing… flickering and staying on steady. Try driving at night without any dash lights… or have them flickering at you…. Makes you feel like you’re gonna have a seizure while driving. I would not recommend these.

Easy to install once you remove the cluster; which wasn't so easy, but not horribly bad. These will fit in socket either direction, but are directional. Since these are led power and common are polarized. What I did was usea multi meter and traced both sides of socket holder on PCB back to wire harness connector and taped 2 stripped wires on to a 9v battery and then stripped the other ends and put them in those pins on harness connector and if it didn't light up I removed the lamp and rotated it 180° and put it back in. Since these are a white light the color of your display does change from Green to a Blue. It does this because there is a blue film on the back of the display and the original lamps were incandescent which is about 3k on the color scale (soft white, yellowish) and since yellow and blue make green that's why your oem color was green. Not sure if you went with a green color lamp if it would be closer to the oem color. Hope you found this helpful.

Easy to install of you are comfortable with getting the gauge cluster out, must power up and reverse bulb polarity of bulb if it doesn’t light up the first time around. Which can be kinda difficult unless you have a tweezer to assist. The lights do dim but not as low as the incandescent bulbs. But it dims low enough to not strain the eyes. I recommend, it adds a new fresh feeling to the vehicle.

So far its been good, haven't had longevity issues yet. Fits the 05 dodge ram 3500 cluster bulbs.

Fit and worked well for my 04 ram. Love the blue.

These lights work great. One thing to note, as others have mentioned, is there is a positive and negative. What I did was put them all in, and then plugged the cluster back into the trucks power (the left most plug in my case). The lights should come on, but depending on how lucky you were with your placement, some may be off. Don’t worry just rotate the bulb that is off 180° and it should come on. Some people suggested that the white ink on the bulb should match the factory bulbs manufacturer stamp, but I found mine did not work that way. It was just a bit of trial and error.
