1157 led bulbs

I have a 69 Chevelle with standard 1157 bulbs in the car. I purchased a set from Pep Boys of 1157 led (i think it had 9 leds in the bulb). The parking lights and brake lights work fine but the turn signals did not. I even tried a different set still no turn signals. Do I need to change anything else. I also did not see any difference of brightness with the led bulbs. Thanks Jerry

Re: 1157 led bulbs

you just wasted your money . led lights draw less juice than a standard bulb. those bulbs are junk if you ask me. there is something you can put in there to make the turn signals work but I would say it is a 1157 bulb

Jerry you need to add a digital flasher so the turn signals work.

1157 led bulbs

This topic just came up the other day. The flasher is mentioned as being needed for the turn signals and it is a drop in replacement for the existing flasher.

Re: 1157 led bulbs

I recently installed white LED lamps from Super Bright Leds, #1157-W26-CBT, $20 each. Turn and stop light is at least as bright as the 1157s. I also installed 3-wire sockets from NPD to assure a good ground connection. This setup did not require a solid state flasher. They draw enough current to flash at a normal rate.
The only problem is that the lamps are cylindrical shape and the lower edge interferes slightly with the metal tabs extending from the socket to hold the socket in place. I bent the tabs away from the lamp base and also squeezed the rolled over end of the tabs. The tabs keep the socket in the mounting hole of the '69 but not tightly. I used silicone RTV type sealant on the socket to hold it in place. A thin blade can be used to slice through the sealant for removal. The RTV (room temperature vulcanizing) sealant is easy to peel off. The '69 housing only allows access to about 180 degrees of the socket base, so use the sealant on just that side.
Super Bright website is one of the few that provide illumination output rating.

Re: 1157 led bulbs

Do I have to order the digital flasher or can it be purchased locally here in Tampa. Thanks for the education. Jerry

Should be able to pick it up local, just ask for a digital flasher not sure if the 4 way flasher is need to be swap out as well or not.

Re: 1157 led

If the LED bulbs are no brighter than the normal 1157 bulbs, why not just stick with the standard 1157 and save the hassle??

Re: 1157 led bulbs

My original setup was clearly not producing enough light. The sockets and ground method were poor. I decided to upgrade all components. I always wanted to try the LEDs. The system works well. I can't drive the car and watch the lights under different conditions. I said they are at least as bright. I don't want to say they are brighter if I can't say how much of an improvement. You really have to see them on the street in the sunlight to judge.

Re: 1157 led bulbs

There's dozens of 1157 LEDs on the market. I have some that are >2X as bright as the incandescent ones they replaced. The bulbs I bought were 550 lumens compared to less than 200 for a replacement incandescent. They were very expensive at about $25 each but worth it to me as they were for my motorcycle and I wanted it to be seen.

Re: 1157 led bulbs

^^^^^^^^^^^^ agree with alan.

look at the Philips bulbs recently released.

also, for LED it is recommend to use same color bulb as lens for the most output.

so you want RED for the tails.

Re: 1157 led bulbs

Rob, I went with white LEDs because they are brighter than the reds in the type I bought. The color looks fine.
