Would you recommend 5k or 6k to match the other oem LED lighting for the VLED's?

 

I would recommend 5K from VLED. We did a Sierra 5000K headlights and 5000K LED fog lamps along with reverse, license plate and cargo and it matches VERY well.

 

The factory LED strips tie in perfectly with the headlights and fogs.

Yeah I have the 55w 5000k for the fog lights but for some reason the 55w wouldn't work for my headlamp and have to use 35w 5000k until they come out with something to make the 55w work with my automatic lights...

 

I just ordered these for the license plate http://www.vleds.com/5k-white-high-power-led-bulbs-194-168-158-1-pair.html.

 

Thanks! Are they hard to put in? I had a company do my Hids

The license plate ones are SO easy!

 

Reach under your rear bumper and feel behind the light > twist the socket to the left and pull out.

 

Remove bulb > install new bulbs and before putting the socket back into the lamp, make sure they both light up as LED's are reverse polarity.

Can someone please explain this disclaimer?

 

WARNING!
Not for use in continuous on applications like dome lights and map lights that can be left on for long periods of time.

 

This is in reference to the 921s from VLEDS

 

 

So if I leave my cargo light on for an extended period of time, is it going to melt the housing?

 

The exception is when the engine is turned off. The cargo and bed lights are on a 10-15 minute timer. Therefore, this is a non-issue.

I wouldn't worry as I'm sure the LED lights run much cooler than the factory bulbs. I did both the cargo and reverse.. it's worth it.. especially the cargo lights.

This kind of disclaimer is usually a sign that the lights are fairly cheaply designed with insufficient heat sinking to allow for continuous duty operation. What'll happen is that the LED die (and then the LED itself) will overheat, dramatically shortening the life of the unit. It won't damage your vehicle. A LED might generate a fraction of the heat per watt compared to an incandescent bulb, but it does require that heat to be efficiently removed from the diode itself- which generally means metal, and requires complexity and expense.

That's one theory... but VLEDs actually makes a high quality product. Another reason for the warning might be due to VLEDs attempt to put as many LEDs as possible in such a small package. The 921's small size limits the amount of heat sink per LED, so it's likely VLEDs made those bulbs for people who want more output and are willing to accept the shorter on duration trade off. I'm one of them.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By newdude · Posted

      Yea that's pretty normal to be off a few degrees.  Usually 2-4 degrees from say a weather app or thermometer.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By studly · Posted

      I just replaced the ambient air temperature sensor.  Easy as pie. I simply had to remove about 10-12 clips on the plastic cover over the radiator and remove two T-10 torx screws on the hood release lever to liberate the cover (Amazingly, none of the clips broke.  All came out and went back in with zero problems). Once the cover was removed, the temp sensor is easily accessible. The sensor cable snakes through a few guides and can be pulled out for even easier access to the sensor. I was able to work the sensor out of the mounting hole.  There is a red sliding catch on the plug that must be pulled back to disconnect the cable.  The plug was quite tight.  I had to use a screwdriver to pry it out. I plugged in the new sensor ($6.45 from RockAuto), snapped it into the mounting hole and re-snaked the cable. I put the radiator cover back on and reattached the lever arm to the hood release.  All done!     I started up my Suburban.  The temperature read 82 °F. Other thermometers at my house read 80 °F.  Close enough.  It might be reading high as my vehicle was sitting in the sun.

      Wow I'm in a pickle. (Broke down truck) and a story.

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, SnapOn can remotely disable the device if it's flagged in their system. And, customer service can tell you if it is, if you're thinking about buying used. B) Make sure it's paid off. If the seller still owes money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid. It's less clear if SnapOn will tell you if a balance is still owed; I didn't make it that far with the used model I was considering. I did read that SnapOn has no way of tracking any "truck financing" deals between the SnapOn rep and buyer, only if they financed through corporate. So there's that extra caution needed.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about. Value, or principles? There's a $1k difference.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.
