JDM ASTARExtremely Bright PX Chipsets White/Yellow 3157 3155 3457 4157 Switchback LED Bulbs For Turn Signal Lights

Absolutely perfect! After trying 2 other cheaper set of switchback bulbs (which either didn't work properly, or failed after a month), these are working exactly as they're supposed to! White running/parking lamps, perfect amber turn signal. The other cheaper switchbacks would trigger white briefly, then switch to amber when turn signals were activated, while running/parking lights were off. Annoying, but I put up with it. I'm very glad they had failed after a month, as I purchased these JDM ASTARs to replace them. WOW what an upgrade!The white running 'mode' is as bright as driving lamps looking at them, and people need to remember that parking lamp housings and lenses don't focus light to the ground. They do light up the ground somewhat, but not like true "driving lamps" do.The functionality of these are spot on. Running/parking lamps on, they're white. If you have no lights on, and use your turn signal, the amber flashes. Brightly! Lock your car, amber. Unlock, amber. No white, not even a flick of white before amber. While your running/parking/head lamps are on, these bulbs are white. Not a blueish light, just a true white light. I'd say closer to 5000k than 6000k. When turn signals are activated, the white turns off, and immediately amber begins to flash. After the turn signal has been cancelled there is a brief pause before the white running light turns back on. Just like newer cars with turn signals near DRL's and headlamps.INSTALL RESISTORS (or replace flasher relay with an LED flasher relay) to avoid hyper-flash. My 2011 Traverse (and most newer GM's, including my 97 Grand Prix) has no flasher relay, as the flashing is controlled by the BCM (Body Control Module)I had installed these bulbs on June 23rd, 2015. They are still working as new, and properly.*UPDATE* - 1-1/2 years after install, and bulbs are still functioning perfectly!*UPDATE* - 4 years later, one bulb has failed. The wire connections are no longer secure inside the end cap, connections fall out of bulb when removed from socket.

I tried two other sets of LED Switchback blubs for my 2014 Dodge Charger RT before this set. The first set (another brand) were defective as the white LEDs would not work when the parking lights were on. The second set (same company but different bulbs) was also defective; the white LEDs worked perfectly but the amber flashing was erratic at best (and yes I have two 50W 6 ohm load resistors installed CUTEQUEEN TRADING 4pcs 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights or DRL (Fix Hyper Flash, Warning Cancellor) (pack of 4)) and at worst, the amber would not work at all. Ordered these, installed them, and they work perfectly. Crisp amber flash when the turn signal is on and nice bright white when the parking lights are on.

These arrived pretty quickly and I couldn't wait to try them out. I purchased a couple different bulb sets for comparison. These are VERY BRIGHT. Installed them in the front turn signal sockets on my 2006 Sienna Limited which has standard sockets (vs. CK) for the front signals.They fit a bit loose even for standard sockets but a small bit of something wedged into the side of the socket where clip holds the bulb to make it tighter was instantly satisfactory. I was able to knock it around quite a bit and it still held strong. These bulbs are considerably longer than the stock incandescent bulbs but for the application they worked out better being longer since they now have better projection.The primary "filament" is white and brighter than the OEM bulb but it's not obnoxiously bright, nor is it distracting to oncoming traffic. When the turn signal is on, they really cut through the night and have better visibility during the day as well.Since these use considerably less current than OEM incandescent bulbs, the turn signal flasher blinks fast but in my case it was not obnoxiously faster. However, I still ordered the LED flasher unit to bring the flash rate back to normal. The flasher hasn't arrived yet so I can't sy anything about it yet.Overall, I'm extremely pleased with these bulbs and have ordered a second set to install in my wife's car.

These are great bright bulbs! They were the perfect replacement for my old incandescent turn signal bulbs. They have worked great as expected, and although I had to buy a resistor kit to keep the bulbs from flashing quickly (hyper flash), they have worked great. I bought and installed these bulbs over A FULL YEAR AGO and they still have been working without a hiccup so I am very happy with the longevity and quality of these LED bulbs. I like the projector as well, it makes a noticeable difference in brightness over the stock bulbs. So, to anyone interested and looking for a better-looking alternative to their regular bulbs I can highly recommend these!

I have this Switchback (running and signal light) for good 9 years and have not miss a beat. Talking about quality and reliability, this is the longest running led light in my mini van by far. No degradation in light output as good as in day one. Super bright and looking like my led headlights and fog lights. Expensive but worth every penny! Highly recommended.

Very bright. Very nice light, functions great.I used them in the rear light of my camper. Good fit. Much brighter than incandescent, making it much safer. Especially when bikes are attached at the back.

Very bright

Went through 4 sets in a year. Some the amber stopped working, some the white running lights quit, and some the entire Unit failed and on one, a few of the leds started to strobe for a week before burning out so only half worked. Switch back to factory bulbs since it wasn't worth the Hassle of wondering if today they were going to burn out and have to remove the fender, grill, etc to change them again.
