Both headlights went out

Hi everyone. First time... just bought an 02 Tundra used with 114K. Love it!! ... just experienced my first problem.... Both low beam headlights went out last night.... looking for some help .... fuses first.... replace bulbs second.... ? then what? I’ll keep you posted after I get back from auto parts

 

Maybe a relay? I’ve had this problem on other vehicles and would take a similar relay that I know to be working and swap them to test.

 

Check out the bulb connectors on the wiring harness

Over time they get brittle and have to be replaced

Please don’t cut the wires!

Just de-pin then and clip back into a new harness plug

Also fill the connectors with Di-electric grease too!


If you need any assistance I’m sure other members can give input as well!!

 

Did they both go it at once? Do the daytime running lights work? High beams work?

 

Ok. Both went out at same time... high beams work... I’m not completely sure if it has daytime running lights..( I don’t think they do) fuses look good.... I located the relay, but not sure if it’s good or bad? But will try switching with similar right now... as well as build connections and bulbs themselves....THANK YOU SO MUCH.... let u know in a few

 

Update.... I switched relay with fog lamp... it appears to be fine.... here’s a pic of the headlight connectors and bulbs.. any clues here?

 

That connection looks corroded!

 

Are those stock bulb watts,or “high output” watt bulbs?

Me personally i kept having issues with my high watts. Once I went back to regular bulbs i stopped having issues.

The high watts caused more heat which in turn cracked/brittles my plugs. I had to replace the plugs.

If everything looks good,maybe a good cleaning of the plug base is in order,and generously fill it with dielectric grease.

If the plug seems kind of loose going onto the bulb,you could always tweak the prongs on the bulb to get a more snug fit. That goes the same for the relays in the relay box as well.

Also cheap Ebay bulbs are what I started out with. They never lasted. I ended up just buying the cheapest stock bulbs Walmart had and have been running fine for years!


A second item to take a look at is your battery ground cables and your short ground cable that screws into the body/comes off the battery.

The above are all issues I have encountered

 

Very nice.... the connections are not bad... it was just grease I was seeing... everything is snug and seems good... I’m gonna check this ground situation and then run and get new bulbs... ( not sure if they are high watts or not... I’m sure I’ll find out shorty... and of course... it’s starting to rain heavy.... thanks again

 

Ok guys.... solution.... 2 new bulbs ... I guess they do go out at same time... I read in another thread.... love this forum...!

 

Paint it black and your headlights will become brighter.

 

Nice looking truck. That's the shell I want on mine.
