Strange...left blinker is acting funky

Hello all! Here to inquire about a potential issue that just occurred earlier this morning on my way to work

Sometime last week my left running daytime light went out so I went to Auto Zone and picked up another replacement bulb. There is a warning where it indicates you need to replace a bulb with increased speed of blinking. I replaced the faulty bulb with a new one and then tested my blinker which went back to its normal speed when blinking. I did no further steps after that other than disconnecting old bulb & connecting the new bulb. Earlier this morning the same left daytime running light went out again (back taillights' blinkers are fine) so I am not sure what is going on? I was at a red light and all of sudden I hear increased blinking when I activated the turn signal.


Does anyone know what could have happened with this? I did nothing different other than going under the truck to disconnect the bulb then put in the new bulb where it tested fine a minute afterwards. Activated turn signal earlier this morning and it is the same thing with the original bulb that went out.


Was there any additional steps I needed to take to make sure my daytime running lights continue working after replacement of one bulb? Thanks guys, I appreciate your time reading my inquiry and I hope to get this issue resolved soon! I'm a huge fan of using turn signals and I feel bad for drivers on the other side of the intersection where we both yield to each other taking opposite turns where they can't see my left front blinker :(

Might have to take it to the stealership if I can't figure this crap out myself! You'd think this kind of situation would include a quick fix where you just swap out bulbs!!

Also, make sure you really shove the bulb into the connector. It will lock in without being fully seated. give it a firm push to lock it down.
 
sounds like:
1) loose bulb
2) short somewhere in the wiring (most likely in the bumper due to exposure)
3) low on blinker fluid.

Seriously, good luck

Had this happen to me. It was a loose bulb (not locked into place)
 
Thanks for all your responses!

So I tested the light and it IS working. However I left the truck via "ON" to test blinker as I messed around with it. It looks like it is loose but for some unknown reason, it will not lock itself into place. I've tried pressing it against the wall to a point where I'm about to crack the bulk due to pressure. Have you guys bought replacement bulbs from Auto Zone for your daytime running lights or elsewhere? I wonder if this particular replacement bulb is compatible with the original one. It is slightly difference in appearance and slightly thicker. Thanks again guys, hopefully I can get this fixed by the end of the day!


edit: it is locked in place (when you twist & turn) but the bulb still comes loose when you're on the road. Especially if I exit the driveway forcing my truck to move a little bit causing the bulb to come loose
 
I just had to replace the socket on mine. The connections were bad causing the bulb to work intermittently. Was a $10 fix from Toyota. The socket just plugs into the wiring harness.

Were you able to figure it out?

yup. been there done that. Fiddled with cleaning the corrosion out several times, then realized they aren't that expensive (I got mine for around $6 ea if I remember correctly). I keep a spares box in my truck with bulbs, fuses, etc, and keep two of these sockets in it.
 
Let us know what worked!

I didn't say anything further for this very reason. I'm embarrassed to say it but I guess you get to find out now



I needed to apply a lot more pressure than minimal pressure I was applying in order to fully connect the bulb :( i didn't want to break the bulb so i was being careful with it at first. Heh
