I failed to add that I used dielectric grease on all connections.

John, would you think Vibratite would remediate the loosening issue?

 

the loosening is the terminals in the plastic, not the threads coming loose. in some cases the female terminal is too big compared to the male. after hours of vibration, the pins wear in the contact location, eventually losing contact. my experience is about 1-5% have this, so its not a major deal.
if there's an o-ring in that connector then i dont think anything else needs done until theres an issue. if theres not o-ring then i would cover with silicone or black permatex after its all connected

 

I still fail to understand the issue you are guys are talking about. It is said a picture is better than 1000 words, do you happen to have any picture that illustrate the problem you are referring to? Also is this specifically from this after market LED vendor? Why this is not an issue on OEM halogen bulbs?

 

i totally agree about the pics. since im in the light lab i took one.
i do throw out the failures, these in the pics are marginal, so no pic of the exact issue at the point of failure
you can see corrosion and contamination because some of these did not have o-rings.
that smallest plastic only connector had an o-ring but needed to have the pins bent.
OEM dont use this connector so not a problem for oem. oem also dont have this type of driver.

 

having 4 pins should reduce the fail rate at a given time.

 

Referring to these connectors and the terminals inside.

 

Thanks alot for sharing the pictures. Now I clearly understand the issue. Applying the dielectric greese on pins will solve the issue?

 

the grease will help keep out contaminants. this connector has an o-ring and that should be good. the grease also helps reduce wear between terminal pins. wont do much for the housing to terminal wear. but, this might not even be an issue because there's 4. and even if something gets loose you can bend a pin or two.

 

FWIW I had these on my 4Runner for about 5 years. Those were Xenon Depot HIDs with the same connectors. I never had an issue with them. Granted, sample size of 1. Their output, connectors, overall quality and customer service is what made me a repeat buyer. I have another set sitting on my work bench for my son's '18 4Runner.

 

Wanting to do this to my newly acquired 12. How hard is it to take the lamp covers off to access the bulbs?

 

Easy,


My only issue is whether the bulbs are the 194 or 168.

 

These should be the same for a 2020 GX, correct? And forgive my ignorance, but are the puddle lights the ones on the inside bottom of the doors?

 

They worked perfect on my 2019, so I see no reason they wouldn’t on a 2020. I also picked up another 8 of the 14’s to do the interior domes and map lights. Huge improvement over the dim yellow stock bulbs. Very happy with the Vled bulbs. Total job took maybe 45 minutes working slowly.

The puddles are the lights near the bottom of each door panel.

 

thank you for the response, I placed my order. vleds states the lights are back ordered until late March

 

I want to replace the bulbs in my Map Lights on my 2010 GX, how do I get the lens off? I hate to start prying and scratch or break the lens and housing.
