Issue with Turning Signal Bulb.

One of my turning signal bulbs burnt out.

I looked up that 4157NA was the bulb size (I have a 2010 TRD Sport) and the switch was pretty simple, but now the new bulbs keep coming loose and then they don't work.

When I push on the bottom of the bulb, it doesn't really click in or anything. I don't see how I can get it seated any further in. Does anyone have any tips on this? Did I get the right size?
Thanks in advance! Every time I drive over some bumps, I lose both my front turning signals so it's super annoying!

 

You can modify your socket to close more. If you are looking at the socket you will see there are two metal "V" that grabs the bulb. Stick a small flat head screw driver in between the metal tab and the plastic housing and push it towards the other metal tab. Do this for both sides on both tabs and you should be good to go.

Here's an image I found online that shows what I was trying to say LOL

 

Worked like a charm, thanks bud!

 

You're welcome. I had to do the same thing when I did my reverse light mod.
